“Think how hard physics would be if particles could think.”

There are no failures. Just experiences and your reactions to them.

One of the most important things you can accomplish is just being yourself.

Just as much as we see in others we have in ourselves.

Minds are like parachutes. They only function when open.

I care not so much what I am to others as what I am to myself. I will be rich by myself, and not by borrowing.

Success is not a good teacher. Failure makes you humble.

The best thing about the future is that it only comes one day at a time.

To fly as fast as thought, you must begin by knowing that you have already arrived.
