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.

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.

Success needs no explanation. Failure does not have one that matters.

I will not be discouraged by failure I will not be elated by success.

Failure is unimportant. It takes courage to make a fool of yourself.

We may be personally defeated, but our principles never!

Success represents the 1% of your work which results from the 99% that is called failure.

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

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

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