I like Dr. Daniel Amen's 18/40/60 Rule: When you're 18, you worry about what everybody is thinking of you; when you're 40, you don't give a darn what anybody thinks of you; when you're 60, you realize nobody's been thinking about you at all. — Jack Canfield Copy Share Image
At the age of 20, we don't care what the world thinks of us; at 30, we worry about what it is thinking of us; at 40, we discover that it wasn't thinking of us at all. — John M Eades Copy Share Image
