”the only way you get a real eduion on the market is to spend cash, monitor your commerce, and study your mistakes...It is emotionally difficult to review your mistakes, since the speculator must wade through his very own poor trades and blunders. And these are not simple blunders; those are blunders that cost money. Anyone who has lost money by investing badly knows how difficult it's to reexamine what occurred. The examination of a losing trade is tortuous but essential to make sure it won't occur again.”
