You can achieve great economic gains by solving social problems.

You can not have significance in this life if it is all about you. You get your significance, you find your joy in life through service and sacrifice - it's pure and simple.

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 most important rule is to play great defense, not great offense. Everyday I assume every position I have is wrong. I know where my stop risk points are going to be. I do that so I can define my maximum drawdown. Hopefully, I spend the rest of the day enjoying positions that are going in my direction. If they are going against me, then I have a game plan for getting out.

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

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.

It is not that we had any unfair knowledge that other people didn't have, it is just that we did our homework. People just don't want to believe that anyone can break away from the crowd and rise above mediocrity.
