What do I do with myself guys?! First world problem!!!!!

I'm 17 years old, it's summer and I am bored everyday. I know, its totally a first world problem but boredom kills especially at my age. I just want my adolescent hood to have some sort of worth. My friends are busy everyday, I have a gym pass, but that only takes up an entire 2 hours. If it wasn't apparent, I'm a guy. Getting my car soon so I've been learning about the mechanics of an automobile - but that gets stale pretty quickly. I'd build something, but I lack the proper tools. Please be understanding and don't get angry because my situation isn't a serious one, it is to me. Can you guys list any hobbies typical (or not so typical) for a guy my age? It means more than you think, and thanks in advance.

TLDR: I'm 17, its summer, and don't know what to do with my life. What do?
