Constant acts of goodness are worth far more than rare acts of greatness.
Always do what you can do instead of worrying about what you can't.
If you want to stay in business, satisfy customers. If you want to excel in business, delight customers.
Be the exception to the rule. It's the surest way to become exceptional.
Make your upper limit, no limit.
Convince people and you win their minds. Inspire people and you win their hearts.
