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

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

If something's important enough, you should try. Even if the probable outcome is failure.

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

People are not remembered by how few times they fail, but by how often they succeed. Every wrong step is another step forward.

No, I haven't failed thousands of times. On the contrary, I have successfully eliminated thousands of ideas that do not work!
