Maturity

"Maturity begins when we're content to feel we're right about something without feeling the necessity to prove someone else is wrong."
-Sydney J. Harris, Syndicated columnist, 1917-1986

"Basically my wife was immature. I'd be at home in the bath and she'd come in and sink my boats."
-Woody Allen

"Man's maturity: to have regained the seriousness that he had as a child at play."
-Friedrich Wilhelm Nietzsche, Beyond Good and Evil
