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

You can't be afraid of failure and you can't be afraid of success, because either one gets in the way of your work.

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

Defeat is not the worst of failures. Not to have tried is the true failure.

We may be personally defeated, but our principles never!

There is no loneliness greater than the loneliness of a failure. The failure is a stranger in his own house.

There's no such thing as failure - just waiting for success.

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.

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

Success needs no explanation. Failure does not have one that matters.
