Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

My great concern is not whether you have failed, but whether you are content with your failure.

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

It's not a very high failure rate if you choose people that you really like the sound of.

Failure is what we're all running from, we're always running toward success with failure at our back.

They who have conquered doubt and fear have conquered failure.

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

There is no loneliness greater than the loneliness of a failure. The failure is a stranger in his own house.

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.

We climb to heaven most often on the ruins of our cherished plans, finding our failures were successes.
