I'm scared to grow up...

You really shouldn't be worrying about this at your age, but if you must, the best thing you can do for yourself, is to develop good habits and discipline yourself. Get some street smarts, and if you have that then you should be fine. Don't get something, unless you need it or you really want it above everything else. That's probably the best you can do for yourself at a young age, also do good in school, although it may get boring, you'll thank yourself later when you're rich.
