We may be personally defeated, but our principles never!

Failure is more frequently from want of energy than want of capital.

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

It's fine to celebrate success but it is more important to heed the lessons of failure.

Do not let your ambitions become a sanctuary for your failures.

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

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.

Failure is not our only punishment for laziness there is also the success of others.

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

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