The destiny of any nation at any given time depends on the opinion of its young people, those under twenty-five.
— Johann Wolfgang von Goethe

The ideas gained by men before they are twenty-five are practically the only ideas they shall have in their lives.
William James twentyfive quote

Twenty to twenty-five! These are the years! Dont be content with things as they are. Dont take No for an answer. Never submit to failure. Do not be fobbed off with mere personal success or acceptance. You will make all kinds of mistakes; but as long as you are generous and true, and also fierce, you cannot hurt the world or even seriously distress her. She was made to be wooed and won by youth. She has lived and thrived only by repeated subjugations.
— Winston Churchill

I shall soon be six-and-twenty. Is there anything in the future that can possibly console us for not being always twenty-five?
— Lord Byron

Broadway, such as I see it now and have seen it for twenty-five years, is a ramp that was conceived by St. Thomas Aquinas while he was yet in the womb. It was meant originally to be used only by snakes and lizards, by the horned toad and the red heron, but when the great Spanish Armada was sunk the human kind wriggled out of the ketch and slopped over, creating by a sort of foul, ignominious squirm and wiggle the cunt-like cleft that runs from the Battery south to the golf links north through the dead and wormy center of Manhattan Island.
— Henry Miller
