How did you become a trader? I think my first related interest was an enthusiasm for poker. As a teenager, I literally earned a living by playing poker. When I first started playing, I read every book I could find on the game and quickly learned that winning was a matter of managing the odds. In other words, if you played only the hands in which the odds were in your favor and folded when they were not, you would end up winning more times than you lost. I memorized the odds of every important card combination, and I was very successful at the game.
