Same mistakes | Please place order - stop loss

My mistakes:

1. BA stock - 10 shares, loss $64
2. GT stock - 700 shares, loss $1500 US dollars
3. BEN stock - 200 shares, loss $140+ dollars
4. SABR stock - Loss $5000+ us dollars
5. INTC $300 US dollars - buy dip 100 shares at $23.90/ share
6. MGM $100 US dollars
7. Do not study business, report, and make sure that I should place an order to stop loss - choose SPX 500 stocks - Be careful
8. Always do one stock very well, do not work on too many stocks - Focus on basic skills - reading, learning, analyzing, examine all steps in orders, review the process, pray, put emotions beside, stay focus
9. Keep learning, and also be humble. 
10. Always have chance to work on another one, set stop loss, do not wait any time. If I forget to set stop loss, then place stop order right away. 
11. Look for other opportunity - move on!
