He's 11. Something happened rather suddenly right around the time of his birthday. He went from not the slightest bit interested in how the computer worked to wanting to code. It's fun!
You are not alone. I've given this advice to several 18-23 year old men:
Jobs are like girlfriends. I'm not trying to be sexist, I'm just speaking from my own perspective as a man. When I was in school, girls I was interested didn't seem interested in me. But then I got a girlfriend. All of a sudden, the girls who wouldn't talk to me started talking to me. It was weird. I'm not saying be a player, I firmly believe that when dating or buying gadgets, once you make a commitment, shopping around will only make you unhappy.
But not with Jobs. Just get a job. Any job. Work at a gas station or bus tables. Do something. You'll feel better about yourself and you take some of the pressure off yourself. And there is some magical aspect to having a job that makes you seem more interesting to employers, kind of like my analogy above with the girlfriend.
In addition to that, consider getting a degree. An AA would be great, a BA/BS would be better. It saddens me that a piece of paper is so important, but that's life. If you're not the type who excels in an institution then figure out ways to get real world experience. If you're a programmer I'd say do some open source development.
Do this in addition to getting a job. As the good book says, "Anyone not willing to work doesn't get to eat." (2 Thes 3:10)
