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.
Failure is more frequently from want of energy than want of capital.
FAILURE, ENERGY THAN WANT OF CAPITAL
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.
