Another part of my problem is that I have too many projects I want to do. Learning about AI is one example, but I've instead done a series of web and mobile apps which are much closer to success. It would take a lot of time to read all the AI research and become good enough to tackle a problem like self-driving cars, and I've only got my spare time at home, with which I must also make sure my wife remains happy (ignoring her seems to make her unhappy for some reason) and keep my sanity (read fiction or play a video game some times) and take care of my house (the lawn just won't stay mowed). I do remember being about 19 and thinking I was the best programmer in the world. By about 22 I had rewritten as much of my old code as I possibly could because it was so horrible. Somewhere between there and now I've gotten a cynical bit of humility to tamper my ego. I think the cynical part is that my ambition has not lessened, just my belief that I can succeed. One Steve Jobs philosophy is focus and say no. I'm guessing I could do better if I said no to all but a single project.
