Life is like riding a bicycle. To keep your balance, you must keep moving.

Anyone who has never made a mistake has never tried anything new.

Everything you can imagine is real.

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.

Reality leaves a lot to the imagination.

I have no special talents. I am only passionately curious.
