Sun-tzu: "If your enemy is superior, evade him. If angry, irritate him. If equally matched, fight, and if not split and reevaluate." (taken from Bud Fox quote in Wall Street 1987)
Jesse Livermore (Wall Street Speculator Legend): "A man must believe in himself and his judgement if he expects to make a living at this game." And, I finally say buy only what you've been so god damn sure. :d '+'
