Logic will get you from A to Z, imagination will get you everywhere.

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

Imagine the end desired and feel its reality. Follow it through, and you will get definite results.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

I am always doing that which I can not do, in order that I may learn how to do it.

Inspiration exists, but it has to find you working.

Reality is merely an illusion.

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

Why does the eye see a thing more clearly in dreams than the imagination when awake?
