They who have conquered doubt and fear have conquered failure.

We may be personally defeated, but our principles never!

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

Success comes when people act together failure tends to happen alone.

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

We have forty million reasons for failure, but not a single excuse.

I don't believe in failure. It is not failure if you enjoyed the process.

Success consists of going from failure to failure without loss of enthusiasm.

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

Admitting failure is quite cleansing, but never - pleasurable.
