The feeble tremble before opinion, the foolish defy it, the wise judge it, the skillful direct it.
Doubt everything at least once, even the sentence “Two times two is four.”
Georg Christoph Lichtenberg
Silence. All human unhappiness comes from not knowing how to stay quietly in a room.
Blaise Pascal (17th century)
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
George Bernard Shaw
Nothing is so firmly believed as what is least known.
Michel Eyquem de Montaigne (16th Century)
The wise don’t expect to find life worth living; they make it that way.
You can’t hold a man down without staying down with him.
Booker T. Washington
