That cotton trade was almost the deal breaker for me. It was at that point that I said, “Mr. Stupid, why risk everything on one trade? Why not make your life a pursuit of happiness rather than pain?

The whole world is simply nothing more than a flow chart for capital.

I always believe that prices move first and fundamentals come second

Where you want to be is always in control, never wishing, always trading, and always first and foremost protecting your ass. That's why most people lose money as individual investors or traders because they're not focusing on losing money. They need to focus on the money that they have at risk and how much capital is at risk in any single investment they have. If everyone spent 90 percent of their time on that, not 90 percent of the time on pie-in-the-sky ideas on how much money they're going to make, then they will be incredibly successful investors.

I believe that great success is possible in any field — from music to mathematics to macro trading.

First if all, never play macho man in the market. Second, never overtrade. My major problem was not the number of points I lost on the trade, but that I was trading far too many contracts relative to the equity in the accounts that I handled.

Fundamentals might be good for the first third or first 50 or 60 percent of a move, but the last third of a great bull market is typically a blow-off, whereas the mania runs wild and prices go parabolic... There is no training, classroom or otherwise, that can prepare for trading the last third of a move, whether it's the end of a bull market or the end of a bear market.
