Failure is not our only punishment for laziness there is also the success of others.

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

Success and failure are both part of life. Both are not permanent.

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

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

Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.

We may be personally defeated, but our principles never!

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

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.

Admitting failure is quite cleansing, but never - pleasurable.
