Why I do not have time to look for those stocks to invest? Docusign, Square, high technology stocks

 I like to look into this issue. Why I did not choose to invest those stocks like Docusign from March 27 to Sept. 27. 2020. 

I like to look into this issue since I compared to my friend I knew near 20 years, who also invests into stock market 20 year who is a retired engineer. 

I like to look into my thinking process. I like to make some improvements.
