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

The only real failure in life is not to be true to the best one knows.

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

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

They who have conquered doubt and fear have conquered failure.

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

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

Outward failure may be a manifested variant of inward success.

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

Success comes when people act together failure tends to happen alone.
