This is how to be your best self:

• "Treat yourself as if you were someone you were responsible for helping."
• To Make Better Decisions, Think Of Your Best Friend: Take the "outside perspective" and follow the advice you would offer a buddy in the same situation.
• For Health, Think About Fido: Look after your health the way people do for their pets, and you'll probably live to be 150.
• For Happiness, Think About Grandmom: Turn the critical voice in your head into a nurturing grandmother and be more self-compassionate.
