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.

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

Our failings sometimes bind us to one another as closely as could virtue itself.

We may be personally defeated, but our principles never!

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

Do not fear mistakes. You will know failure. Continue to reach out.

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

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

The great question is not whether you have failed, but whether you are content with failure.

Admitting failure is quite cleansing, but never - pleasurable.
