I recognize Albert Einstein not only as a great physicist but also as a master of words. So here are some great quotes:
"The true sign of intelligence is not knowledge but imagination."
"Life is like riding a bicycle. To keep your balance, you must keep moving."
"We cannot solve our problems with the same thinking we used when we created them."
And last but not least: one of the greatest:
"Only two things are infinite, the universe and human stupidity, and I'm not sure about the former."
