Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off the bowlines, Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream.
You live and learn. At any rate, you live.
A clean desk is a sign of an empty mind.
Wisdom begins in wonder.
You can tell whether a man is clever by his answers. You can tell whether a man is wise by his questions.
The mind has exactly the same power as the hands: not merely to grasp the world, but to change it.
No man is an island, entire of itself; every man is a piece of the continent.
A bookstore is one of the only pieces of evidence we have that people are still thinking.
The mind is not a vessel to be filled but a fire to be kindled.
When all men think alike, no one thinks very much.
