Working out: If possible I highly advise finding a workout partner. I lift weights with a (now-ex) co-worker, and it makes the workout significantly more enjoyable, and provides motivation to keep me going, even on days he can't make it (don't want to fall behind!).

Alternatively, consider a class. A dance class can be great for both 1 & 7 (note: don't be that guy who hits on every woman in your class, no one likes that guy), but it could be anything, martial arts, gymnastics/ninja warrior, racketball, etc.
