Exercise: Don't do things other people tell you to do. Do things you think might be fun. Don't run, don't go to the gym. Sign up for Taekwondo, Pilates, dancing or swimming lessons.

If something is worth doing it's worth doing right: If you really want to learn something spend at least 15 minutes every day studying it. If you can't commit to that, stop wasting your time.

Some university classes are boring but that's not a reason to dismiss them. You never know what knowledge might become useful to you a few years down the road.
