I am looking for a lot of men who have an infinite capacity to not know what can't be done.

We don't want tradition. We want to live in the present and the only history that is worth a tinker's dam is the history we make today.

Some people think they can; some think they can't. They are probably both right.

Life is a series of experiences, each one of which makes us bigger, even though sometimes it is hard to realize this.

Thinking is the hardest work there is, which is probably the reason why so few engage in it.

Anyone who keeps learning stays young.

A business absolutely devoted to service will have only one worry about profits. They will be embarrassingly large.
