Earlier quoted context omitted.
Probably a dumb question but when I watch poker on TV I see that the aggressive players tend to win, so why do the losers let themselves get intimidated?
In poker, like in trading, the key is knowing when you have an edge and being aggressive but also knowing when you have a losing have and cut your losses. It's the balance that makes a good player/trader.
So basically "You've got to know when to hold 'em, know when to fold 'em, Know when to walk away, know when to run." :)
