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

Most people say that it is the intellect which makes a great scientist. They are wrong: it is character.

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

If you cannot do great things, do small things in a great way.

The greatest way to live with honor in this world is to be what we pretend to be.

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

That some achieve great success, is proof to all that others can achieve it as well.

Great minds discuss ideas average minds discuss events small minds discuss people.

My success was not based so much on any great intelligence but on great common sense.

All difficult things have their origin in that which is easy, and great things in that which is small.
