That some achieve great success is proof to all that others can achieve it as well.

My success is due more to my ability to work continuously on one thing without stopping than to any other single quality.

Success is the result of hard work.

I failed my way to success.

I never did anything by accident, nor did any of my inventions come by accident; they came by work.

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