Elbert Hubbard

The line between failure and success is so fine that we scarcely know when we pass it: so fine that we are often on the line and do not know it.

A failure is a man who has blundered, but is not able to cash in the experience.

Optimism is a kind of heart stimulant – the digitalis of failure.

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.
