It's nice to have a game that sells a million copies.

One of the big lessons of a big project is you don't want people that aren't really programmers programming, you'll suffer for it!

Honestly, I spend very little time thinking about past events, and I certainly don't have them ranked in any way. I look back and think that I have done a lot of good work over the years, but I am much more excited about what the future holds.

Programming is not a zero-sum game. Teaching something to a fellow programmer doesn't take it away from you. I'm happy to share what I can, because I'm in it for the love of programming.

Low-level programming is good for the programmer's soul.

Focused, hard work is the real key to success. Keep your eyes on the goal, and just keep taking the next step towards completing it. If you aren't sure which way to do something, do it both ways and see which works better.

In the information age, the barriers [to entry into programming] just aren't there. The barriers are self imposed. If you want to set off and go develop some grand new thing, you don't need millions of dollars of capitalization. You need enough pizza and Diet Coke to stick in your refrigerator, a cheap PC to work on, and the dedication to go through with it. We slept on floors. We waded across rivers.
