They who have conquered doubt and fear have conquered failure.

Failure is more frequently from want of energy than want of capital.

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

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

Do not fear mistakes. You will know failure. Continue to reach out.

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

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

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

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

Success consists of going from failure to failure without loss of enthusiasm.
