Success is stumbling from failure to failure with no loss of enthusiasm.

You become strong by defying defeat and by turning loss and failure into success.

The biggest failure of man is that he gives up before he realizes how close he was to success.

Success is falling nine times and getting up ten.

Of course I would have preferred success; but failing in that, I have no regrets for having rejected all advice to the contrary, and resolutely made the struggle.

Each time you fail, you have eliminated another wrong option.
