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

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.

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

I don't believe in failure. It is not failure if you enjoyed the process.

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.

It's not a very high failure rate if you choose people that you really like the sound of.

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

They who have conquered doubt and fear have conquered failure.

Every adversity, every failure, every heartache carries with it the seed on an equal or greater benefit.

Outward failure may be a manifested variant of inward success.
