When I was about 12, a girl in my class liked to point out my problems. I was too thin; I wasn’t a good student; I talked too much, I was too 46 , and so on. At last, I became very angry and ran to my father. He listened to me 47 . Then he asked, "Are these things true or not? Do you know what you are really like? Go and make a 48 of what she said and find the 49 that are true." I did as he told me. To my great 50 , I discovered that about half of the things were true. Some of them I couldn’t change (like being very thin). But there were things I could and wanted to change. For the 51 time, I got a clear 52 of myself. I brought the list back to Dad. He refused to take it. "That’s just for you. " he said, "You know the truth about 53 better than anyone else. When people say something that is true about you, you should find it helpful. " Our world is full of people who think they know your business. Don’t 54 your ears and feel 55 . Listen to them.
