Like anything you do you have to be committed and determined to be successful. It's not a dark secret that there are no short cuts in life. This article assumes we are all much dumber than I prefer to believe we are. We being people who have money to trade stocks and suffer from big losses.
I learned how to trade stocks by reading books about value investing and accounting practices. Very simple stuff that like anything worth learning takes a bit of time and effort. I don't get the upvotes on this article.
