Just be a leader whether you are an officer or not. HAVE FUN . If it's not fun, it's not worth it, plain and simple. College is too short to be involved in a club that isn't exciting or causes stress. Spend your time elsewhere.
School comes first .
If you are not doing well in your classes, it is ok to say that you cannot handle it. In fact, doing so is very respectable. Get involved for yourself. Do not get involved because people tell you to, or because your mom, brother or sister were involved in college. Get involved because you want to make a difference in your own life and in someone else's.
