Learn one stock exceptionally well, how it trades, how it responds, it's nuance, it's personality, and watch and study it every day, every hour of the day. Watch it. Set up a paper account and trade it daily. See how it reacts to market moves, to macro news, etc. After 6 months of doing this start learning several indicators. Master those indicators. Then start to apply them to your one stock, and study them for 6 months. You will see set-ups, points of entry and exit. You will be able to handle any kind of SPX/NASX perturbation. After doing this for about 3 years you will have a reliable source of compounding income. I did this for the past 3 years and it's a remarkable source of revenue.
Only master one stock, make it your second child, that's all you need.
