With me I must back my opinions with my money. My losses have taught me that I must not begin to advance until I am sure I shall not have to retreat. But if I cannot advance I do not move at all. I do not mean by this that a man should not limit his losses when he is wrong. He should. But that should not breed indecision. All my life I have made mistakes, but in losing money I have gained experience and accumulated a lot of valuable don’ts. I have been flat broke several times, but my loss has never been a total loss. Otherwise, I wouldn’t be here now. I always knew I would have another chance and that I would not make the same mistake a second time. I believed in myself.
A man must believe in himself and hi judgement if he expects to make a living at this game. That is why I don’t believe in tips.
