I build things because I like to build them, I want to use them, and on some level, probably a bigger level than I’m willing to admit, I want other people to use them.

I started writing software (not all that long ago) because the act of doing it is fun. You code something, see if it works, it does (in a way), you celebrate, and try to fix it. Wash. Rinse. Repeat.

Knowledge and productivity are like compound interest. Given two people of approximately the same ability and one person who works ten percent more than the other, the latter will more than twice outproduce the former. The more you know, the more you learn; the more you learn, the more you can do; the more you can do, the more the opportunity - it is very much like compound interest. I don’t want to give you a rate, but it is a very high rate. Given two people with exactly the same ability, the one person who manages day in and day out to get in one more hour of thinking will be tremendously more productive over a lifetime.

I like it when competitors copy me because it means they aren’t about to leapfrog me: they’ll always be playing catch-up.

Talent hits a target no one else can hit; Genius hits a target no one else can see.
