How long until you are competent?

I'm a high school senior who is very interested in programming as a backup option for if my acceptance to music school does not happen, or happens with too little scholarship money to afford it. I'm pretty big on math, and have done a bit of Learn Python The Hard Way. I guess my question is, with or without college, how long does it seem to take until most people are able to begin programming for money?

I know it's a lifelong-learning experience, but surely there has to be a point in which you can support yourself on your work.

Sorry guys, I'm new here. If you don't mind me asking >>7 , what exactly makes me a "Zionist Jew"? I am confused because nothing in my post suggested I was Jewish, or religious at all for that matter.

Also, I'm sure Java isn't the best language out there. I know it's been quite painful for me many days(read: months). That being said I do honestly enjoy the feeling of solving problems with the kind of creativity that object oriented languages allow. What language do you prefer >>6 ?
