Thomas Edison

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

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

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

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

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