I grew up in a socialist country. And I have seen what that does to people. There is no hope, no freedom. No pride in achievement.

I had an extremely boring time doing 20 to 30 trades a day while everyone was talking about baseball or basketball. So I stood there fantasizing about a device that could do the same thing I was doing.

Some traders still think that a computer could not trade as well as they can.

I paid $1.9 billion in taxes in my lifetime.

It seems like people don't learn from the past.

Never bend the rules. You bend the rules a little bit and then it's a slippery slope.

I see no point in exchanging something that I understand, know, love and think will have a great future for something else that I know much less about.
