Balance is about doing what you need to do and then having fun. Not that tough, ok? Do important stuff first, and then frag. This is gloriously uncomplicated.
So what is important? I have no idea. For me, important stuff is (in order):
Taking care of my family
Working and making money
Progressing in my career
Taking care of myself (part of this is having fun)
Participating in a meaningful spiritual community
Keeping up with the d&d 4e rules
Learning how to rocket jump in tf2
