that's very true ,and it is also applicable to business,once you fail just pick up the challenge and move on ,learn from your own mistakes and failure,and never to repeat that sane mistake again ,I believe with these things one can have a successful businessI strongly accept this because it reminds me back then when I was in school there is one particular subject am not good in and it makes me repeat the class but no one tell me what to do next is to study more so that I will pass at the end so the same goes to business as well.
