They who have conquered doubt and fear have conquered failure.

Once you can accept failure, you can have fun and success.

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

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

If you're not failing every now and again, it's a sign you're not doing anything very innovative.

Failure is not fatal, but failure to change might be.

Failure seldom stops you. What stops you is the fear of failure.

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

It is not a disgrace to fail. Failing is one of the greatest arts in the world.

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