The document contains several quotes about failure:
- "Ever tried. Ever failed. No matter. Try Again. Fail again. Fail better." (Samuel Beckett)
- "To recognize that the greatest error is not to have tried and failed, but that in trying, we did not give it our best effort." (Gene Kranz)
- "It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something." (Franklin D. Roosevelt)
