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.

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

There is no loneliness greater than the loneliness of a failure. The failure is a stranger in his own house.

Failure is what we're all running from, we're always running toward success with failure at our back.

The most important of my discoveries have been suggested to me by my failures.

Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.

It's fine to celebrate success but it is more important to heed the lessons of failure.

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

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

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