The following is an excerpt from Jesse Livermore’s “Reminiscensces of a Stock Operator,” which is available in our public domain library.
It takes a man a long time to learn all the lessons of all his mistakes. They say there are two sides to everything. But there is only one side to the stock market; and it is not the bull side or the bear side, but the right side. It took me longer to get that general principle fixed firmly in my mind than it did most of the more technical phases of the game of stock speculation.
I have heard of people who amuse themselves conducting imaginary operations in the stock market to prove with imaginary dollars how right they are. Sometimes these ghost gamblers make millions. It is very easy to be a plunger that way. It is like the old story of the man who was going to fight a duel the next day.
His second asked him, “Are you a good shot?”
“Well,” said the duelist, “I can snap the stem of a wineglass at twenty paces,” and he looked modest.
“That’s all very well,” said the unimpressed second. “But can you snap the stem of the wineglass while the wineglass is pointing a loaded pistol straight at your heart?”
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 his judgment if he expects to make a living at this game. That is why I don’t believe in tips. If I buy stocks on Smith’s tip I must sell those same stocks on Smith’s tip. I am depending on him. Suppose Smith is away on a holiday when the selling time comes around? No, sir, nobody can make big money on what someone else tells him to do. I know from experience that nobody can give me a tip or a series of tips that will make more money for me than my own judgment. It took me five years to learn to play the game intelligently enough to make big money when I was right.
