I'd say don't sweat it. Make sure to not focus too much on computers. Programming/entrepreneurship is great and interesting, but I know that I spent a lot of my early teens as a loner in front of my computer screen.
Also, I'd say finish. Whatever it is that you do, finish it. Don't let abandoning stuff become a habit.
