Drumming is an excellent way to express yourself, and also a way of communication. You can do it really loud and fierce if you're mad (just please, don't hurt anyone or the drums -- you won't feel any better). If you know a sad song you can play that when sad. And it's a good way to spend your time when you have finished your homework. (No skipping work to play: responsibility comes first, as well as good time management.)

You can be in a band, or make a band. Drumming is an awesome hobby to do also just for fun. I love the feeling of being able to create music in such a simple way as playing a drum. It relieves my stress, as well as makes a wall of peace and calm around my mind.
