I would advise continuing to work on skills using the insane amount of online resources available. While also working to build up an open-source profile of side-projects. Side projects not only show that you truly do enjoy developing, but they also provide a great tangible means for exemplifying your skills. You have a great jump on learning these skills but because of your age you will need tangible proof that you have real skill. Because of this I think open-source side projects are a perfect fit. They're fun, hone your skills, and prove you can create (and maintain, document, etc.) a software system.

Oh and I can't agree enough with all the people saying savor the time. I can remember countless days where I was 'bored' stiff all day, while nowadays I find myself dreaming of being able to not have to sleep daily so I could fit in even more hours for projects, both personal and professional.

I firmly believe that as you age your perceived notion of time passing only accelerates.
