Boredom is the root of all evil - the despairing refusal to be oneself.

The only real mistake is the one from which we learn nothing.

Every intelligent individual wants to know what makes him tick, and yet is at once fascinated and frustrated by the fact that oneself is the most difficult of all things to know.

The greatest pride, or the greatest despondency, is the greatest ignorance of one's self.

There are two educations. One should teach us how to make a living and the other how to live.

The object of the superior man is truth.

There are no limitations to the mind except those we acknowledge.

Colorless green ideas sleep furiously

Experience is merely the name men gave to their mistakes.

Thoughts without content are empty, intuitions without concepts are blind.

To do great things is difficult, but to command great things is more difficult.

Realize deeply that the present moment is all you ever have.

Experience keeps a dear school, but fools will learn in no other.

Yes, I guess you could say I am a loner, but I feel more lonely in a crowed room with boring people than I feel on my own.

I am a lover of truth, a worshipper of freedom, a celebrant at the altar of language and purity and tolerance.

The only real laughter comes from despair.
