Used to watch my dad come back from work and stay glued to the television tracking the tickers. I used to help him keep track of a few stocks as well. Slowly got interested and picked up some random book that explains the stock market terminologies.
The #1 takeaway from the book is "Before you buy the stock, give an elevator speech with facts(data-driven) and reasons as to why this stock is going to be a good buy."
Turns out a lot of my investments don't stand this test!
