Imagination is more important than knowledge. For while knowledge defines all we currently know and understand, imagination points to all we might yet discover and create.

Reality is merely an illusion, albeit a very persistent one.

A person who never made a mistake never tried anything new.

Genius is the ability to make the complex simple.

The heresy of one age becomes the orthodoxy of the next.

By nature man hates change; seldom will he quit his old home till it has actually fallen around his ears.

Keep hope alive!
