I learned how to play poker at a very young age. My father taught me the concept of playing the percentage hands. You don’t just play every hand and stay through every card, because if you do, you will have a much higher probability of losing. You should play the good hands, and drop out of the poor hands, forfeiting the ante. When more of the cards are on the table and you have a very strong hand–in other words, when you feel the percentages are skewed in your favor–you raise and play the hand to the hilt.

The most important is discipline–I am sure everyone tells you that. Second, you have have patience; if you have a good trade on, you have to be able to stay with it. Third, you need courage to go into the market, and courage comes from adequate capitalization. Fourth, you must have a willingness to lose; that is also related to adequate capitalization. Fifth, you need a strong desire to win.

Paul Tudor Jones

Everything gets destroyed a hundred times faster than it is built up. It takes one day to tear down something that may have taken ten years to build. If the economy starts to go with the kind of leverage that is in it, it will deteriorate so fast that people’s heads will spin. I hate to believe it, but in my gut that is what I think is going to happen.

Don’t ever average losers. Decrease your trading volume when you are trading poorly; increase your trading volume when you are trading well. Never trade in situations where you don’t have control. For example, I don’t risk significant amounts of money in front of key reports, since that is gambling, not trading.

If you have a losing position that is making you uncomfortable, the solution is very simple: Get out, because you always get back in. There is nothing better than a fresh start.

Don’t be too concerned with where you got into a position. The only relevant question is whether you are bullish or bearish on the position that day.
