Ok, I'm ten years older, I'll give some advice. You're 17, you're just starting to get good at stuff, so don't sweat it so much. I think the best thing to do is take on an interesting, challenging project that has some potential to become a product, but will definitely push you to learn. Hell, copy someone else's idea. As you work on it, you'll probably figure out something they aren't doing, or find a product that rests between the competition. For now, becoming a great hacker is more important than having a winning idea, because if you do it in the reverse order, you may not be able to implement said idea...
