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

Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.

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

They who have conquered doubt and fear have conquered failure.

Success and failure are both part of life. Both are not permanent.

You cannot climb the ladder of success dressed in the costume of failure.

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

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

Defeat is not the worst of failures. Not to have tried is the true failure.

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