We may be personally defeated, but our principles never!

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

It's how you deal with failure that determines how you achieve success.

Success consists of going from failure to failure without loss of enthusiasm.

Our failings sometimes bind us to one another as closely as could virtue itself.

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

I think success has no rules, but you can learn a great deal from failure.

It's not a very high failure rate if you choose people that you really like the sound of.

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

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