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

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

Failure doesn't kill you... it increases your desire to make something happen.

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

Success is never final, failure is never fatal. It's courage that counts.

Failure is nature's plan to prepare you for great responsibilities.

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

I can accept failure, everyone fails at something. But I can't accept not trying.

They who have conquered doubt and fear have conquered failure.

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