...I've known many men who were right at
exactly the right time, and began buying or selling stocks when prices were at the very
level which should show the greatest profit. And their experience invariably matched
mine that is, they made no real money out of it. Men who can both be right and sit tight are uncommon. I found it one of the hardest things to learn. But it is only after a stock operator has firmly grasped this that he can make big money. It is literally true that millions come easier to a trader after he knows how to trade than hundreds did in the days of his ignorance"...Jesse Livermore
