Everybody will have their idols in their heart. For me, I am a teenager, of course I will chase the star. Someday, when I was walking on the street, I heard a wonderful song from the store, so I remembered the singer. I searched the information and listened to all his songs. I was crazy about the singer, I even imagined meeting him someday. The most unbelievable thing was that I wrote a letter to him though I did not send out. But as the time went by, my attention on him was less and less, at last, I chased another star. I realized paying much attention on the star was wasting the time, I needed to do my own thing.
