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

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

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

Do not let your ambitions become a sanctuary for your failures.

We have forty million reasons for failure, but not a single excuse.

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

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

There's no such thing as failure - just waiting for success.

Success comes when people act together failure tends to happen alone.

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