Your only 15 once. Enjoy life to the fullest. Your only in high school, you have plenty of time to think of what you want to be in the future. You'll be successful in life if you willing to be successful. "Dream as you'll live forever, live as you'll die today", James Dean. All of the greatest authors started off will nothing, just work your way up, try looking up an well known author and see how they have come to greatness (try Stephen king).
