Put yourself first today, and don't you dare feel guilty about it! Sure, you could spend your time helping someone with a tough project, listening to a friend's latest dramas, or helping a relative move. But so what? You can't be at the beck and call of other people all the time. If you made plans to treat yourself, then it's okay if that takes precedence. No one will feel abandoned or let down if you take care of yourself. They understand more than you think they do.
