It always seems impossible until it's done.

Everything you can imagine is real.

Only put off until tomorrow what you are willing to die having left undone.

Everything is a miracle. It is a miracle that one does not melt in one's bath.

What one does is what counts. Not what one had the intention of doing.

Inspiration exists, but it has to find you working.

Bad artists copy. Good artists steal.

What we usually consider as impossible are simply engineering problems, there's no law of physics preventing them.

He can who thinks he can, and he can't who thinks he can't. This is an inexorable, indisputable law.
