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.

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

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

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

Outward failure may be a manifested variant of inward success.

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

It is not a disgrace to fail. Failing is one of the greatest arts in the world.

We may be personally defeated, but our principles never!

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

Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.
