The power of time can be a double edged sword. The user will correct what he wants, but what about his present reality? would it still remain the same?
Its nice to see how that failure shaped you. You didn't only seat up, but you are currently nailing any English exams you seat for. Thats impressive. But what if you didn't fail? would you be as serious as you are? would you seat up and learn more than you could have learnt if you didn't fail? I think when you look at it from that perspective, failure can be said to be a good thing too. I guess.
