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

Failure is simply a few errors in judgment, repeated every day.

We may be personally defeated, but our principles never!

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

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

Failure is the condiment that gives success its flavor.

You can't be afraid of failure and you can't be afraid of success, because either one gets in the way of your work.

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

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

Enjoy failure and learn from it. You can never learn from success.
