Haven't been on the board for a while but thought I'd give an update. I have decided to try and do both. I actually got Matt Brown's email address and asked him what advice he could give me. I won't share the whole email but I will share a few things he told me.
1) Communicate and prioritize. At some point schedules will conflict. Decide which activity is more important and communicate that to the coaches and battalion.
2) Be present where you are. Give all of your attention to whatever you are doing. If you're in class pay attention so that you'll have to spend less time studying later.
3) Be humble. The other Cadets will see that you get excused from some functions, which may cause some animosity. He found that by being humble, fellow Cadets will respect you rather than be jealous.
Thanks for the advice and information that I received. I'll try to do periodic updates for anyone who is interested.
