Larry Ellison: I decided to go into the computer business in college. I started working part-time programming. I found that in a very short period of time, I could make more money writing programs than a tenured professor at the University of Chicago was making, and I was a teenager. I said, “Well, this is kind of cool.” It was also fun, it was like a big game, it was like working on puzzles. So I enjoyed it. It paid extremely well, I could work at home, I could work my own hours. I closely associated with computers, because they were absolutely a slave to reason, they knew nothing about fashion. They were completely logical. I enjoyed spending time with them. I liked what I was doing, it was very profitable, and it was very creative. It was also giving me immediate feedback. I could start writing a program, and within several hours, I could have a result. Freud defines maturity as the ability to defer gratification. The great thing about programming is you don’t have to be mature at all. You don’t have to defer gratification for more than a few hours. You get wonderful, tight feedback. It’s a lot of fun. That’s characteristic of games and sports. The reason why games and sports are so popular is because you win or lose very quickly. You get immediate feedback. It’s a very tight loop, you don’t wait hours or days or years before you find out if you’re winning or losing. You find out a second-and-a-half after you release that basketball. You know whether it’s going in or not.
