The best thing is to write as much as possible. Pick up as many projects as you can, design and recreate everything you have read about in computer science literature. Keep coding fun and do it as much as possible. Find the reference material used to teach computer science courses (there are standard books for many areas). READ READ READ. Diversify your knowledge into areas you find interesting. All you need is diligence. You may find that by the time you're in your early 20s you are light years ahead of your peers.
