A failure is a man who has blundered but is not capable of cashing in on the experience.
There is no failure except in no longer trying.
To avoid criticism, do nothing, say nothing, be nothing.
A little more persistence, a little more effort, and what seemed hopeless failure may turn to glorious success.
The final proof of greatness lies in being able to endure criticism without resentment.
The greatest mistake you can make in life is to be continually fearing you will make one.
