liyanchang's suggestion is bang on. Even if you never touch on it again, if you actually force yourself (by working on an interesting project) to touch on the full stack of an app you will benefit from it for years. So many of the little hobby projects I've worked on over the years (long since abandoned) have provided a fantastic base for something else. A website I managed when I was a teenager taught me all sorts of server admin skills that still pay off 5 years later. When you're 15 you have absolutely oodles of free time (it might not seem that way now, but it will when you're working full time!). Make use of it!
