What's the best way to approach clubs in college?
Go to as many initial meetings as possible. Meet the people, get a vibe for what they're doing, and decide then whether you could see yourself long-term in that club. You don't have to stay/join all of them, but try out as many as you can. If you end up sticking with one or two, that will fill your time plenty. Just get a feel for it and then decide!
