Bottom line is, I didn't return to Apple to make a fortune. I've been very lucky in my life and already have one. When I was 25, my net worth was $100 million or so. I decided then that I wasn't going to let it ruin my life. There's no way you could ever spend it all, and I don't view wealth as something that validates my intelligence.
There are places I want to visit where if I'm wearing a baseball cap and some sunglasses I think I can get away with and mingle in a crowd.
