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.

They who have conquered doubt and fear have conquered failure.

Failure is not fatal, but failure to change might be.

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

If you're not failing every now and again, it's a sign you're not doing anything very innovative.

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

Failure is the condiment that gives success its flavor.

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.

We may be personally defeated, but our principles never!

Success is never final, failure is never fatal. It's courage that counts.
