How to make $3000 grow, which method should I use?

ok, I’m 18 and I have saved $ 3 500 from work. Plus I have about $ 300 in an account with a card that I actually use. I don’t need the $ 3000 now and probably won’t for like 4 or 5 years. So, what is the best option to do with that money rather than leave it in my account?

trust fund?
any other ideas??? please, it will help if you elaborate too, thanks
