5 minutes sharing: Willingdon church Chinese eagle reunion sharing

Nov. 30, 2019

Introduction


It is our reunion and we met at Formosa academy. We used to get together in Willingdon church starting from December 2010. After 2016, we stopped get-together, now it is 10 year reunion.

Get-together


We have 45 adults and 25 kids, now the old kids are 8 years old.

I am so glad to meet those friends again. Most of them grew up, married, with kids, one person left in 2013 and came back with wife and 4 year old son. I am still the same, work in the same job last 10 years, and still rent a small bedroom last 10 years. I am getting old, kind of easy to forget things, people's name, and all other things. My eye bleed yesterday and it is hard for me.

I did not attend Willingdon church starting from Nov. 2018 after I chose to start to work on personal finance. I felt so touched by so many friends, and so happy to watch them to grow into middle 30s or close to 40 years old, best years in their life.

What I shared is the story how I landed in Canada from 2010, how I find Willingdon church and met in the small group Willingdom Chinese single group.

I went to road trip 14 days to Vancouver in 2010, on the road trip to Yosemite, I got a call from my friend in Florida, and her classmate purchased a home in 47th st., so that was my first home. I rented a small bedroom, and attended the church they went. In December, I started to join Willingdon church. That year I was 44 years old.

I was naive and I chose to attend younger people single group instead of my age group. I learned that at the time people in the group are young and lack of business skills or other things. I also was cheated every year to go to same Chinese auto shop, my car's brake would not work, and I went back to the shop; I asked to change the engine oil, the Chinese mechanic let go my brake oil. I still went back. I did see a lot of issues in my skills to live and do business in Vancouver.

I talked about a few things from 2010 to 2017. I talked about car accident and I got hit from behind, the accident and what the accident taught me.

I talked about last meeting I asked Angela, what if I purchased a condo, then I could not afford it. She told me to sell it.

Now the condo price is doubled, after 10 years in Vancouver, I plan to migrate to other city, cheap house and then I should think about retirement. I am over the hill.

I talked about the behavior I had did not match my age. My college classmate told me that I should not do things people do in 28 years old, like her son working in Amazon Seattle. I asked what she did, one time she told me that she invests on stock market.

I did not attend the church after Nov. 2018, I was involved a lot of personal finance research. I am back in stock market. I did not learn from 2010 to 2018. I was stubborn and then now it is hard for me to learn the lesson how to invest.

This reunion reminded me that I should go back to attend Christian get-together.

My ten year home as a renter in the city of Vancouver

June 30, 2019

Introduction


It is time for me to review my last 10 years as a renter in the city of Vancouver. I stay the same place from 2010 December to Nov. 30, 2019. I like to write a case study about my renting experience.

10 years renting

I came to Vancouver on April 14, 2010. I went to Yosemite national park, I travel with my friend on 14 days road trip. I got a call from Florida, my friend called me and told me that her high school classmate just bought a house in 47th ave, it was empty and they were working on renovation of bathroom. So I got my first home in the east Vancouver. I stayed there until Dec. 2010.

I moved to second place in the city of Vancouver, less than 1 mile away from my first home 47th ave.



2019 June - 2019 November six month baby investor

Nov. 30, 2019


Introduction


It is very stressful to stay in the stock market even though I already know all the analysis of my own portfolios, I did research based on Canada retirement guide and do believe that the research makes sense. The road to take risk is tough, one thing I can manage is to stay in the market one year and learn from one year experience.

My portfolios


I already stayed in the market over 6 months. I totally felt good last 10 years to let fund stay in bank with 1% interest or no interest, but stay in the market and go up and down, I feel stressful. It is called loss aversion.

I had painful experience in short time in 2001 and in 2009. But I did not think carefully, over 20% loss, and then put all my USA fund in IRA CD or money market fund over 10 years. Even though each year only less than 1% interest.

It is called stubborn, getting old, no more learning in my personal finance. It is hard for me to push myself to advance in my career, so I chose to work on personal finance instead. Now I feel that it is tough to live a life like staying in market.

I can push myself to stay in the market one year. I will see how many things I learn, every time I feel stressful, I will try to learn something new on personal finance.

Actionable items


Based on my experience in 2001 and 2009, I did not invest enough time to learn investment. I just did the investment and managed my 401 K and IRA. I did not fully review every year. So this bad habit of personal finance caused me struggle last 23 years in north America.

It is better for me to invest time to learn basics first. I learned how to work on algorithm and data structure last five years, I like to use those experience to work on my personal finance as well.



Case study: I got a red eye

Nov. 30, 2019

Introduction


It is tough for me to catch up health management. I recently was busy at work and my own projects , but I got a red eye starting from Nov. 29, 2019. Life is tough when I have a red eye. I can feel the stress and pain around my eye last two days.

One picture worth million words


I also had a few instances of headache around August first time in my life. I had a few times and I went to see walk-in clinics.

Right now I have to look into possible issues related to this incident.





Case study: Comparison to engineers in Sillicon Valley

Nov. 30, 2019

Introduction


It is no surprise that I will meet very talent engineers on interviewing.io as an interviewer. I have to hold high standards, but I also am hard working super talent programmer, I should treat people with fairness. Hard working, good test skills, problem solving is very important, I am not searching top 5% on weekly contest on Leetcode.com.

Case study


I decided to make changes. Last three months I just used two algorithms to test so many engineers. Yesterday I decided to ask two new algorithms. 

I asked two algorithms in last six month weekly contest. I also failed or struggled to solve in weekly contest. So the interviewee performed much better than me. He solved both of them.

Today I learned that he is principle engineer in a very big hardware company in Sillicon Valley.

I met so many engineers working for Amazon, Facebook, Google and Oracle; every time I was surprised to learn that those people will beat me to compete a job based on coding interviews.

Side Hustle review

Here is the link.

What I want to share today is "Side Hustle," a book whose theme is about entrepreneurship, but I will focus on where any job can be applied. SIDE HUSTLE's Chinese is "Reunification." In my opinion, the word "rehabilitation" represents multiple occupations or diversified sources of income. In addition, it also has the meaning of "copying" to duplicate one's own ability and bring about a new source of income. Therefore, I give a definition of "business recovery": give play to your existing ability and create a source of income other than the principal job. How to do it? The way I recommend 4 o'clock in the movie.





I like to make money while I sleep

Nov. 30, 2019

Introduction


It is my personal finance research. I like to learn how to invest on stock market based on index fund, I like to take risk and push myself to feel comfortable to put my 80% saving in Canada into Questrade instead of Scotia bank. I have to push myself to learn how to make money while I sleep.

Toughest project 


I have to believe the knowledge is power. The more I learn, the more I earn.

Here are my highlights to invest on stock market index funds, how busy I was to catch up to learn, being able to manage $62,000 Canadian dollars into stock market, and also I manage $26,000 US dollars 401 K and IRA account.

1. Work on risk, volatility and worst case of my portfolio
2. Work on time the market, time in the market research
3. Work on my psychology of investment, and I like to be a happy long term investor.
4. Work on management of condo in Florida. I have to study market and find best tenants I can and maintain good relationship with tenants.

Actionable Items


It is most important for me to get educated in finance literacy. I should prepare worst case scenario, and then I can make money while I sleep. Bear market will not last more than three  years. After three years, I will learn how to invest better and learn the value of patience and wealth grown with USA economy.





Case study: I cut my own hair in 2019 to save time and $10 dollars each cut

Nov. 30, 2019


Introduction


It is time for me to push myself to take more risk to accumulate wealth, I started to invest into index fund in May 2019. And also I cut my own hair, and then like to save one hour and also $10.00 dollars.


Case study


It is hard for me to catch up good hair style. I like to try various ideas to maintain my hair style. I know that it is much more important to keep me more healthy and spend more time to play sports.

Case study: a small lobster meal

Nov. 30, 2019

Introduction


It is my breakfast. I cooked the small lobster and had my breakfast. It is long time since I had a lobster. This is the first one in my last 10 years in Canada.

Learn to be frugal


I had hard time to think about my right eye yesterday. It was bleeding and my last time is left eye in October. The duration is less than two months.

I have to look into the issue.

I just chose a small remedy to purchase a lobster in Costco to entertain myself. Life is tough. I need to keep myself healthy. I need to look into the issue.

In October, I went to Google GHC event, I got my friend's home after 12:00 AM, I let my trunk lid hit my head. Next two days my left eye bleed.


Case study: How to be a sponsor as a lonely Canadian?

Nov. 30, 2019

Introduction


It is my personal finance research. I study millionaire mindset, I read the book, but I often think about how to be a sponsor as a lonely Canadian. How to support my nephew a 25 year old to start his life in Canada?

Debate


It is very serious topic. I have to think again and again. I have to evaluate how much I can spend and support since I turned 53 years old last Month.

I do believe that I should let it go. My brother can afford the payment of $250,000 Chinese yuan for a car, he can pay more than five people salary in the city of Yichun, Jiangxi province, as a small business owner. I should think about myself how to settle down in Canada.

I think that a young person does not work and stay at home more than three years, he has problems to get into society. He could not take a minimum pay job, and then he will have tough time to face reality in Canada.

Life is tough here in Canada.

Cal Newport: "So Good They Can't Ignore You" | Talks at Google

Google talk. Here is the link.

"Follow Your Passion" is Bad Advice. Here is What You Should Do Instead... In this eye-opening account, Cal Newport debunks the long-held belief that "follow your passion" is good advice. Not only is the cliche flawed -- preexisting passions are rare and have little to do with how most people end up loving their work -- but it can also be dangerous, leading to anxiety and chronic job hopping. After making his case against passion, Newport sets out on a quest to discover the reality of how people end up loving what they do. Spending time with organic farmers, venture capitalists, screenwriters, freelance computer programmers, and others who admitted to deriving great satisfaction from their work, Newport uncovers the strategies they used and the pitfalls they avoided in developing their compelling careers. Matching your job to a preexisting passion does not matter, he reveals. Passion comes after you put in the hard work to become excellent at something valuable, not before. In other words, what you do for a living is much less important than how you do it. With a title taken from the comedian Steve Martin, who once said his advice for aspiring entertainers was to "be so good they can't ignore you," Cal Newport's clearly written manifesto is mandatory reading for anyone fretting about what to do with their life, or frustrated by their current job situation and eager to find a fresh new way to take control of their livelihood. He provides an evidence-based blueprint for creating work you love. SO GOOD THEY CAN'T IGNORE YOU will change the way we think about our careers, happiness, and the crafting of a remarkable life.

The hidden costs of early RRSP withdrawals

Here is the link.

3. Permanent loss of contribution room

When you withdraw funds from an RRSP, you permanently lose the contribution room you originally used to make your deposit. While you can continue making your maximum contribution to your RRSP in the future, you can’t re-contribute the amount you withdrew. This reduces the potential value of your RRSP at retirement.

TFSA - how to think about tax issues?

Nov. 28, 2019

Introduction


I was confused about TFSA about tax issues after I read Canada government website. So I continued to do research, I found a good article to explain tax issue very clearly. 

TFSA - tax issues


Here is the article. 

With a tax-free savings account (TFSA), you can grow your money with various kinds of investments, including bonds, stocks, mutual funds and exchange-traded funds – not just cash. Your investment return could potentially be in the high single- or even the low double-digits, if your investments perform well. Or you could lose money, if they don’t. Just keep an eye on your contribution limit, which currently stands at $5,500 per year (and rises to $6,000 per year in 2019), in addition to whatever you had withdrawn from your TFSA in an earlier year and are now re-contributing. Unlike RRSP contributions, your TFSA contributions aren’t tax deductible. But because you’ve already paid income tax on the money you put in your TFSA, you won’t have to pay tax when you take it out. And any investment income you earn won’t be taxed – not even when you take the money out of your TFSA.

While a TFSA offers tax-free growth, the restrictions on the investments you hold in it might mean it will take a few days to withdraw your money. This could be highly inconvenient if the rain is pouring through the hole in your roof in the meantime, or your car has broken down hundreds of miles from home.
To cover such situations, you could keep some money in a high-interest savings account. While these don’t offer the growth potential of a TFSA because you can’t hold investments in them, they do pay slightly more interest than an ordinary savings account. The interest you get depends on your bank and your balance. Since your money isn’t locked in, it’s much easier to get at when you need it. Unlike a TFSA, there’s no limit to the amount you can put in a high-interest savings account, but you do have to pay income tax on the interest you earn. Note that you can have a registered high-interest savings account itself as a TFSA, in which case TFSA contribution limits and tax treatment apply.
Not sure what’s right for you? An advisor can help you decide which savings option (it could be more than one) can help you grow your money during good times and have it on hand when hard times come along.

Should you put your money in a TFSA or an RRSP?

Here is the article.


How to avoid these 4 common TFSA mistakes

Here is the article.

It’s easy to see why. As the name says, any investment you hold inside your TFSA grows tax-free. Plus, you can withdraw from these accounts whenever you want. You can use your TFSA to help pay for a new homeyour children’s education or even retirement. And you’re not taxed when you take the money out, either.


6 really useful things you can do with your TFSA

Here is the article.

My takeaway is the following:

You can “refill” your TFSA. Unlike RRSPs, RESPs or any other registered accounts, your TFSA contribution limit isn’t a one-time thing. Suppose, for example, you’ve contributed the maximum to your TFSA this year, but then need to withdraw $10,000. (Remembering, of course, that there’s no tax on the withdrawal, whether you’re withdrawing principal, interest or investment growth.) Next year, in addition to the regular annual contribution limit, you’ll be able to re-contribute that $10,000. Just don’t try re-contributing in the same calendar year that you take it out, if you’ve already used up that year’s contribution room.

124. Binary Tree Maximum Path Sum

Here is the link.

C# mock interview practice on Nov 24, 2019 with insights

Nov 25, 2019
It is one of my mock interview algorithms. I solved the algorithm but I also experienced the nervousness since I could not remember if I solved the algorithm before. It is a hard level algorithm, and I like to write down how to approach the algorithm in the contest or mock interview or onsite.
I solved all tree algorithms on Leetcode six months ago. But my generic approach is to solve all easy level algorithms on Leetcode.com first, and then move to medium level. So it is important for me to explain how to approach this hard level algorithm since I solved similar easy level tree algorithm called longest univalue path, my discussion post is here. I am still in the accumulation stage to solve as many algorithms as possible. Be greedy, solve easy one, solve one with less time first, solve ones to help me build confidence, increase curiosity, and expand my comfortable zone.
Case study
I like to go over the example and explain to myself how to approach the problem. Let me show some diagram with my thought process in my mock interview.
image
I like to go over the example, and explain how I ask question what to do based on example 2.
image
After the work out on example 2, I learned that I need to work on an extra task to calculate the path cross the root node. The whole process from example 1 and example 2 took me around 10 to 15 minutes.
If you cannot follow the process, then I can advice you to review the post I have about longest univalue path. Here is the link.
I spent two months to interview people on interiviewing.io using a few binary tree algorithms almost every weekday, I learn and work every day on tree algorithms. Those interviewees are best teachers in the world and they brought all their education and industry experience to demonstrate how good thinkers are, I learn to build up my curiousity and be a real problem solver, open to all ideas as an interviewer and determin to make the idea work, remove bias and avoid memorization of a solution, ask good questions to follow the idea and understand the question.

財務自由的人生:跟著首席分析師楊應超學華爾街的投資技巧和工作效率,40歲就過FIRE的優質生活


4%法則
每年花40萬,25倍就是一千萬
保守點可以多準備1~2年生活費
薪水存10%要51年才能退休,
存20%要37年,
存30%要28年,
存40%要22年,
存50%要17年,
存60%要12.5年,
存70%要8.5年,
一直做一樣的事情,卻期待有不一樣的結果
一般事業頂峰40~50歲,50歲前退休,可以多存點錢
資產配置很重要
簡單的資產配置 股債比 100-年齡
ETF指數為主 買基金比挑個股安全省事:連巴菲特都幫老婆買 ETF,費用低又不用煩惱
建立多方的收入來源:雞蛋不要全放在同一個籃子裡
用債券或高配息股票提供穩定的定期收入
光靠省錢很難達到財務自由
問題不是費用,而是營收:開源比節流重要,去高薪但你沒聽過的工作
最好50歲前存好退休金,社會很現實,公司可以輕易找到一個比你年輕、做同樣事情的年輕人,以你一半的薪水取代你
沒有行動,一切都是白說
設定高目標,即使不到月球,也會飛到星星附近
永不滿足,別懼失敗:Stay Hungry, Stay Foolish
吸引力法則和目標設定:先相信,才會看見
要改變你的狀況,要先改變你的想法
有計劃的設定目標
一萬小時法則
把自己的時間管理好,專注在高價值的事
設立目標後,要先有理由,行動才容易恆久
FIRE最終的目的是建立健康快樂、有目的的人生:身心健康,才是真自由
