I have tried 99 times and have failed, but on the 100th time came success.

Do not allow yourselves to be disheartened by any failure as long as you have done your best.

There is no failure except failure to serve one's purpose.

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

Don't take 'no' for an answer, never submit to failure. Do not be fobbed off with mere personal success or acceptance. You will make all kinds of mistakes, but as long as you are generous and true, and also fierce, you cannot hurt the world or events.

Great success always comes at the risk of enormous failure.
