Success is the product of the severest kind of mental and physical application.

Thomas Alva Edison

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

I'm either going to go completely mental, completely bankrupt, or have the best success of my life.

I failed my way to success.

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

Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.

I owe my success to the fact that I never had a clock in my workroom.
