不必再勉强

If the cell turned into cancer, chemo it, laser it, get rid of it from our body, we dont keep harmful thing around us, do we?

If an apple got rotten, remove from the fridge, throw it away. No matter how good your fridge is, it wont stop the apple further deteriorate. A rotten apple wont turn fresh anymore, will it?

If the branch does not bear fruit, chop it, cut it or break it from the tree. It is probably genetically wrong that is for nobody to rectify.

If people turn sour for no reason, for god sake, waste no time, leave and leave forever. There are many sweet people worth our life to spend time with. If ever a sour people turn sweet again, that only make him a freak. Could it be misunderstanding or something? Yes, for the first time, maybe the second too. But, third time means cancer cell, a rotten apple, withered branch, wasting only time.

这都是同一个道理。。。 不做勉强的事。东西坏了就坏了， 不必再勉强做些什么。
