Learn from the mistakes of others. You won't live long enough to make them all yourself. If you and your partner always agree, one of you is unnecessary. Not to decide is to decide. Yesterday is history.
Tomorrow is a mystery.
Today is a gift. That's why we call it 'The Present'. Always try to drive so that your license will expire before you do. Be sincere, even if you don't mean it. It's hard to be humble when you're perfect.
