We may be personally defeated, but our principles never!

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

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.

I think that failure by your own standards is certainly a form of success.

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

Remember that failure is an event, not a person.

It's not necessary to fear the prospect of failure but to be determined not to fail.

I think success has no rules, but you can learn a great deal from failure.

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

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
