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.

I don't believe in failure. It is not failure if you enjoyed the process.

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

We have forty million reasons for failure, but not a single excuse.

Do not let your ambitions become a sanctuary for your failures.

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

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.

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

Failure seldom stops you. What stops you is the fear of failure.
