Fifteen is such a weird age to be. Nobody treats you like an adult, but you desperately want to be one. You still have these childlike aspects, but you're just kind of coming into the world.
Everybody wants to be famous, but nobody wants to do the work. I live by that. You grind hard so you can play hard. At the end of the day, you put all the work in, and eventually it'll pay off. It could be in a year, it could be in 30 years. Eventually, your hard work will pay off.
