Three Rules to Live By

If you could choose three rules to live by, what would they be?

Mine:

1. [Good] information is power (but ignorance is bliss)
2. The only thing to fear is fear itself
3. KISS (Keep it simple, stupid)

Addendum: 4. Nothing is good or bad but thinking makes it so

Addendum: 5. The brain loathes uncertainty (more of a statement that can be used to predict things...)

Addendum: 6. For every action there is an equal and opposite reaction

Addendum 7. The things you own end of owning you

Addendum: 8. There is no more sincerer love than the love of food

Addendum: 9. Good health is true wealth

Addendum: 10. Relax
