We all want ourselves to do be good at something. I guess the problem is sometimes that we want to reach our goal -the impossible- too fast. We think about it and we're going for it with as a result that we place the necessary and the possible on the second place. While when you want to reach the impossible, you have to "start by doing what's necessary; then do what's possible; and suddenly you are doing the impossible".
Never forget this order, sweeties!
