Rest

When you are tired, you may do or say things you regret.  It is not a time for making decisions or promises.  It is a time for rest.  Inform those around you of your condition in a gentle way.  Tell them that you will be there for them after you get some rest, and then get some rest.  Seek balance.  Listen to the body.  Treat it with love and gratitude.  Honor the self.  If you play hard or serve greatly, seek balance so as not to undo the good things you have enjoyed.  Yes, such simple and obvious advice, but advice that often goes unheeded.
