Failure is the condiment that gives success its flavor.

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

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

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

Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.

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

Outward failure may be a manifested variant of inward success.

Failure is unimportant. It takes courage to make a fool of yourself.

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

Success needs no explanation. Failure does not have one that matters.
