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

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

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.

We may be personally defeated, but our principles never!

Once you can accept failure, you can have fun and success.

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

They who have conquered doubt and fear have conquered failure.

Failure is not our only punishment for laziness there is also the success of others.

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.

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