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.

To do the job right requires such an enormous amount of concentration. It’s physically and emotionally mandatory that you find some time to relax. And you’ve got to be able to turn it off like that. There will be times though that I get so incredibly excited about a trade or even a project that I’ll wake up at 4 o’clock in the morning and there’s no way in hell that I’m going back to sleep. I’ll sit there in my dreams and trade for four hours.

I’d say that my investment philosophy is that I don’t take a lot of risk, I look for opportunities with tremendously skewed reward-risk opportunities. Don’t ever let them get into your pocket - that means there’s no reason to leverage substantially. There’s no reason to take substantial amounts of financial risk ever, because you should always be able to find something where you can skew the reward risk relationship so greatly in your favor that you can take a variety of small investments with great reward risk opportunities that should give you minimum draw down pain and maximum upside opportunities.

It was at that point I said, “Mr. Stupid, why risk everything on one trade? Why not make your life a pursuit of happiness rather than pain?” That was when I first decided I had to learn discipline and money management. It was a cathartic experience for me, in the sense that I went to the edge, questioned my very ability as a trader, and decided that I was not going to quit. I was determined to come back and fight. I decided that I was going to become a very disciplined and business like about my trading.
