What's your opinion in the quote "success is moving from failure to failure without losing your enthusiasm"?

I would say that I agree with the quote, as I believe in the 8020 rule where a person fails first 80 times and from the 81th time he will carry the experience and reasons of failing the 80 times and he will not repeat them in future and will be successful in the next 20 times. SO he moved from failure to failure 80 times without losing the enthusiasm to succeed.
