The first requisite of success is the ability to apply your physical and mental energies to one problem without growing weary.

Today, I am wondering what would have happened to me by now, if, fifty years ago, some fluent talker had converted me to the theory of the eight-hour day and convinced me that it was not fair to my fellow-workers to put forth my best efforts in my work? I am glad that the eight-hour day had not been invented when I was a young man. If my life had been made up of eight-hour days, I don't believe I could have accomplished a great deal.

Nature made us - nature did it all - not the gods of the religions.

I know this world is ruled by infinite intelligence. Everything that surrounds us- everything that exists - proves that there are infinite laws behind it. There can be no denying this fact. It is mathematical in its precision.

My main purpose in life is to make money so I can afford to go on creating more inventions.

What a man's mind can create, man's character can control.
