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.

The great question is not whether you have failed, but whether you are content with failure.

We climb to heaven most often on the ruins of our cherished plans, finding our failures were successes.

Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

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

We may be personally defeated, but our principles never!

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

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

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

Failure doesn't kill you... it increases your desire to make something happen.
