Not to mention that the more you are involved with organized activities, the more chances you'll have to network with people. Who knows, you might meet an employer! My friend took a waiter position while we were in school to network, and he ended up getting a dream job at Boeing because of it (and also because he's brilliant).
I once hired a girl who was a waitress at my favorite restaurant. She was finishing a degree and I had an opening. She was a great hire. You never know who you'll meet. Good luck!
