“I have not failed. I've just found 10,000 ways that won't work.”

Many of life's failures are people who did not realize how close they were to success when they gave up.

Opportunity is missed by most because it is dressed in overalls and looks like work.

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

Genius is one percent inspiration and ninety-nine percent perspiration.

If we did the things we are capable of, we would astound ourselves.

As long as your going to be thinking anyway, think big.
