The secret of change is to focus all of your energy, not on fighting the old, but on building the new.

Be as you wish to seem.

It's not what you are that holds you back, it's what you think you are not.

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

Where there is shouting, there is no true knowledge.

My brain is only a receiver, in the Universe there is a core from which we obtain knowledge, strength and inspiration. I have not penetrated into the secrets of this core, but I know that it exists.

Death may be the greatest of all human blessings.

There's no one thing that's true. It's all true.

If you tell the truth, you don't have to remember anything.
