Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.

It's fine to celebrate success but it is more important to heed the lessons of failure.

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

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

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.

My great concern is not whether you have failed, but whether you are content with your failure.

It's not necessary to fear the prospect of failure but to be determined not to fail.

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