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.

Defeat is not the worst of failures. Not to have tried is the true failure.

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

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

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

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.

I will not be discouraged by failure I will not be elated by success.

Success is not final, failure is not fatal: it is the courage to continue that counts.

You cannot climb the ladder of success dressed in the costume of failure.

Success represents the 1% of your work which results from the 99% that is called failure.
