While being busy can be a good thing, don't over commit. Fall is such a fantastic time on campus, especially with the many events. Remember, though, you don't have to do everything your first semester! You have four years to try a variety of new activities. And right now, to be the student you need to be, you still need to build time into your schedule to sleep, study, eat healthy and exercise (even if it's just walking to class).
Find the right balance between adventure, your new freedom and remaining successful academically. The Success Coaching program can help.
