Sure. Google for a good manual or tutorial. Learn that the satisfaction of programming comes from solving challenging problems yourself. That in itself will help you in so many aspects of both computer science and programming, you'd be suprised.
If you feel offended by this post, you should really read the excellent document by Eric S. Raymond entitled Asking Good Questions (I think, or something along those lines). I'm sure you can find it on Raymond's site.
