Admitting failure is quite cleansing, but never - pleasurable.

We may be personally defeated, but our principles never!

Success is not final, failure is not fatal: it is the courage to continue that counts.

Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.

The great question is not whether you have failed, but whether you are content with failure.

Success is never final, failure is never fatal. It's courage that counts.

Do not fear mistakes. You will know failure. Continue to reach out.

I think that failure by your own standards is certainly a form of success.

The most important of my discoveries have been suggested to me by my failures.

The only real failure in life is not to be true to the best one knows.
