Quotes from the same author

Friendship, like credit, is highest when it is not used.
Never explain - your friends do not need it and your enemies will not believe you anyway.
A little more persistence, a little more effort, and what seemed hopeless failure may turn to glorious success.
There is no failure except in no longer trying.
A failure is a man who has blundered but is not capable of cashing in on the experience.
