I can accept failure, everyone fails at something. But I can't accept not trying.

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

Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.

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

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

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

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

We may be personally defeated, but our principles never!

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

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