College college college college. Your 20s are when you figure out what you want to do. College is expensive but a great way to dabble in tons of stuff, socialize, and get ready for the next step. Being 21 isn't too late, plenty of people go to college at 21-22 after stints in the military. You'll be popular as you'll be able to buy your friends beer (legal disclaimer: don't do that).
