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.

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

They who have conquered doubt and fear have conquered failure.

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

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

Failure is not our only punishment for laziness there is also the success of others.

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

Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.

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