I am in exact accord with the belief of Thomas Edison that spirit is immortal, that there is a continuing center of character in each personality. But I don't know what spirit is, nor matter either. I suspect they are forms of the same thing. I never could see anything in this reputed antagonism between spirit and matter. To me this is the most beautiful, the most satisfactory from a scientific standpoint, the most logical theory of life.

Whether we think we can or cannot, we are right.

The government in business may waste time and money without rendering service. In the end the public pays in taxes. The corporation cannot waste or it will fall. It cannot make unfair rulings or give high-handed, expensive service, for there are not enough people willing to accept inferior service to make a volume of business that will pay dividends.

Whatever you have, you must either use or lose.

He who believes he can and he who believes he cannot are both correct.

The whole secret of a successful life is to find out what is one's destiny to do, and then do it.

People are as happy as they choose to be.
