Success is going from failure to failure without loss of enthusiasm.

Take time to deliberate, but when the time for action comes, stop thinking and go in.

Be interesting, be enthusiastic... and don't talk too much.

By failing to prepare, you are preparing to fail.

If it's me against 48, I feel sorry for the 48.

I will prepare and some day my chance will come.

You gain strength, courage and confidence by every experience in which you really stop to look fear in the face.... You must do the thing you think you cannot do.

Pleasure in the job puts perfection in the work.

To copy others is necessary, but to copy oneself is pathetic

Never make excuses. Your friends don't need them and your foes won't believe them.

If you think of yourselves as helpless and ineffectual, it is certain that you will create a despotic government to be your master. The wise despot, therefore, maintains among his subjects a popular sense that they are helpless and ineffectual.

To solve any problem, here are three questions to ask yourself: First, what could I do? Second, what could I read? And third, who could I ask?

The secret of success is constancy to purpose.

Listen if you want to be heard

Percentages are why I am rich.

If you're bored with life, if you don't get up every morning with a burning desire to do things, you don't have enough goals.

You can't just ask customers what they want and then try to give that to them. By the time you get it built, they'll want something new.

A person who never made a mistake never tried anything new.

Of all the things I've done, the most vital is coordinating those who work with me and aiming their efforts at a certain goal

Do one thing at a time, and while doing it put your whole soul into it to the exclusion of all else.

Action is the foundational key to all success.
