rely on ourselves which were outside the mirror

  I have already finished reading the book now.What impressed me most is "the Mirror of Erised" in which Harry can see his dead parents while Ron only can see himself as a head boy.
  "It shows us nothing more or less than the deepest ,most desperate desire of our hearts."Professor Dumbledore said. Harry ,who has never known his family ,sees them standing around him.Ron, who has always been overshadowed by his brothers,sees himself standing alone, the best of all of them.However,this mirror will give them neither knowledge or truth.Men have wasted away before it ,entrance by what they have seen,or been driven mad,not knowing if what it shows is real or even possible.Harry also once addicted to the unreal image of his parents in the mirror,fortunately Dumbledore told him the turth,so that he can catch the Sorcerer's Stone through the mirror in the end.
  Only the happiest man on earth would be able to use the Mirror of Erised like a normal mirror,that is ,he would look into it and see himself exactly as he is.Yet everybody has a desire. We want to be happy,but we will not be happy for all kinds of things.It is difficult for the real word to meet all of people's dreams,as a consequence,we can see someone addicted to the virtual word in the Internet, and some parents put their hopes in their children.However, whether through the Internet or through children to achieve the desires of "I",was not real me.
  To make ourselves happy, we have to rely on ourselves which were outside the mirror.
