In Yes and No all things consist.~Jakob Böhme

I only have "yes" men around me. Who needs "no" men?~Mae West

Go not to elves for counsel, for they will say both no and yes.~J.R.R. Tolkien

The art of leadership is saying no, not saying yes. It is very easy to say yes.~Tony Blair

The formula for my happiness: a Yes, a No, a straight line, a goal.~Friederich Nietzsche

To say yes, you have to sweat and roll up your sleeves and plunge both hands into life up to the elbows. It is easy to say no, even if saying no means death.~Jean Anouilh

When you say Yes, say it quickly. But always take a half hour to say No, so you can understand the other fellow's side.
~Francis Cardinal Spellman

"Yes" shuts us in. "No" sets us free.
~Mason Cooley

The screaming silence of no's knife in yes's wound.
~Samuel Beckett

There is the grand truth about Nathaniel Hawthorne. He says NO! in thunder; but the Devil himself cannot make him say yes. For all men who say yes, lie; and all men who say no,—why, they are in the happy condition of judicious, unincumbered travellers in Europe; they cross the frontiers into Eternity with nothing but a carpet-bag,—that is to say, the Ego. Whereas those yes-gentry, they travel with heaps of baggage, and, damn them! they will never get through the Custom House.
~Herman Melville
