Warren Buffett

I'd rather be a could-be if I cannot be an are; because a could-be is a maybe who is reaching for a star. I'd rather be a has-been than a might-have-been, by far; for a might have-been has never been, but a has was once an are.
Milton Berle

Niccolo Machiavelli

The new ruler must determine all the injuries that he will need to inflict. He must inflict them once and for all.
Niccolo Machiavelli

The mind, once expanded to the dimensions of larger ideas, never returns to its original size.

Each player must accept the cards life deals him or her: but once they are in hand, he or she alone must decide how to play the cards in order to win the game.
Voltaire
