Good? Bad? There is only the value that you place on your own time. It may be that shaving/maintaining friendships/health do not offer rewards that you value. That's your decision. In the end, if your occupation doesn't reward you in a way you value, you will find an alternative way to spend your time.

edit: If you are concerned about how you spend your time, I would suggest that you should spend some time reflecting on why you are making those choices.
