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

Every adversity, every failure, every heartache carries with it the seed on an equal or greater benefit.

Failure is what we're all running from, we're always running toward success with failure at our back.

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

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

We may be personally defeated, but our principles never!

Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.

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

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

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