The real secret of success is enthusiasm.

To me every hour of the day and night is an unspeakably perfect miracle.

It devolves upon the United States to help motorize the world.

Whenever there is a hard job to be done I assign it to a lazy man; he is sure to find an easy way of doing it.

I am sorry about the person who is not truly excited about his job. He will not only never truly be happy there, but he won't achieve anything great.

Well, some people create their own opportunities; others go where opportunities are the greatest; others fail to recognize opportunity when they are face to face with it.

The real secret of success is enthusiasm.
