If you can keep on trying after three failures in a given undertaking you may consider yourself a 'suspect' as a potential leader in your chosen occupation. If you can keep on trying after a dozen failures the seed of a genius is germinating within your soul.

One of the most essential yet the hardest truths that I have had to learn is that every person should be his own hardest task-master.

To become successful you must be a person of action. Merely to "know" is not sufficient. It is necessary both to know and do.

The man who always takes and never gives is not a leader. He is a parasite.

If you do not believe in co-operation, look what happens to a wagon that loses a wheel.

Effort only fully releases its reward after a person refuses to quit.

The only trouble with this world today lies in our lack of understanding of the power of imagination.
