Thomas Edison on Work

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

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

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

Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.

There is no substitute for hard work.

- Thomas Edison, American inventor
