Ideally, we'd all have the intrinsic drive to make the best grades possible, focus our energy on tasks and projects that are useful to ourselves and our community, explore new interests, and push ourselves to become stronger leaders. But life just doesn't work that way. For most of us, the best way to look like we have that intrinsic motivation is to set ourselves up with some extrinsic forces to push us into more discipline. If you want to be a strong student, want to learn more about leadership, and want to volunteer to help others...but don't always get around to it, then joining a group that enforces scholarship, leadership, and outreach can be a very smart thing to do.
