I never did anything by accident, nor did any of my inventions come by accident; they came by work.
I never did anything worth doing 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.
Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.
There is time for everything.
