The avant-garde spirit is not just a youthful sentiment — I live my life by it.

What you think about day and night forms your character and personality.

Admire as much as you can, most people don't admire enough.

Knowledge is limited. Imagination encircles the world.

Intuition is a very powerful thing, more powerful than intellect.

Pretend you’re more obsessed with this moment and a little bit less with the way it ends.

Tolerance, like any aspect of peace, is forever a work in progress.

Learning never exhausts the mind.

Don’t try to figure out what other people want to hear from you; figure out what you have to say.

We are all of us obliged... to nurse a few little follies in ourselves.

It is not enough to know your craft — you have to have feeling.

What you do makes a difference, and you have to decide what kind of difference you want to make.
