7 Cardinal Rules of Life

Someone posted this on Facebook so I have no idea of its origin.  I know that I like it and think we'd all be so much happier if we could follow these rules:

1. Make peace with your past....so it won't screw up the present.
   
2. What others think of you....is none of your business.
   
3. Time heals almost everything....give it time.
   
4. Don't compare your life to others....and don't judge them.  You have no idea what their journey is all about.
   
5. Stop thinking too much....it's alright not to know the answers.  They will come to you when you least expect it.
6. No one is in charge of your happiness....except you.
7. Smile....You don't own all the problems in the world.

and if I could add my own to make it 8 Rules I would add this one:
  8.  Let go of being right....having to be right is not compatible with a happy and peaceful life, and it's annoying!
