The greatest good you can do for another is not just to share your riches but to reveal to him his own.

Dreams must be heeded and accepted. For a great many of them come true.

Some are born great, some achieve greatness, and some have greatness thrust upon them.

A great part of courage is the courage of having done the thing before.

People with great gifts are easy to find, but symmetrical and balanced ones never.

Nothing great in the world has ever been accomplished without passion.
