(Minus a couple of personal-life details ^_^)
First off, I’m actually perfectly well off. I live in a good-sized house, with a nice yard, with deer occasionally showing up and eating the roses (my wife likes the roses more, I like the deer more, so we don’t really mind). I’ve got three kids, and I know I can pay for their education. What more do I need? The thing is, being a good programmer actually pays pretty well; being acknowledged as being world-class pays even better. I simply didn’t need to start a commercial company. And it’s just about the least interesting thing I can even imagine. I absolutely hate paperwork. I couldn’t take care of employees if I tried. A company that I started would never have succeeded -- it’s simply not what I’m interested in! So instead, I have a very good life, doing something that I think is really interesting, and something that I think actually matters for people, not just me. And that makes me feel good.
