Wouldn't life loose meaning then? If you never had to try, sorta? If everything you dreamed about, you could do. That leaves no room for improvement, new ideas, realization etc. But, i do like the idea, nonetheless. I would take all my tests happily, knowing i couldn't fail.
hmmnnnuuu... You can't succeed at failing, or you would have succeeded -- but you can't fail at failing either, because you would have succeeded in failing, rendering the failure a success, which would make the failed attempt to fail fail at failing...!
