There is only one way to avoid criticism: do nothing, say nothing, and be nothing

Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.

Hell is—other people!

If you don't know where you're going, any road'll take you there.

Failure is simply the opportunity to begin again, this time more intelligently.

Life is a progress, and not a station.

The truth will set you free, but first it will piss you off.
