My favorite quotes:

"Imagination is more important than knowledge."

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

"Creativity is intelligence having fun."

"Everybody is a genius. But if   you judge a fish by its ability to climb a tree it will live its whole life believing  it is stupid."

"We cannot solve our problems with the same thinking we used when we created them."

"if you can't explain it simply, you don't understand it well enough."

"Logic will get you from A to B, Imagination will take you everywhere."

"The intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift."
