　　My favorite book, The Secret by Rhonda Byrne, talt a formula called “SFF” which stands for “stopping finding faults”. I used to be a critical person and tried to find faults. I guess I somehow inherited this character from my father. Actually many good qualities of my father are worth admiring except this.
　　My father is the person who constantly looks for mistakes in other people and he thinks no one is perfect in the world. His character created a negative atmosphere in my family. I was the same as my father, so I often felt angry, disappointed, depressed, and lonely in school.
　　After I had read my favorite book I began to seek “good things” in other people. It has completely changed my life. Now I feel happier, I have more friends, I have more trust in people, and I realize everyone has their own strength! Another important lesson I got from this book is that I should always behave myself in a positive manner. Let’s admit that we sometimes complain about our situation. That’s not good. “Believe it or not, people don’t like to listen to negative opinions.”
　　One more valuable lesson I got from the book is that I should be a good listener. When I was younger, I only wanted people to pay whole attention to my words so that I could show them how important I was. I was very proud and would show off my achievements in school without considering others’ feeling. I had very few friends and most people considered me as an “arrogant” person. Now, I find it mush easier to make friends after making some changes!
　　4. Why does the author like the book The Secret?
　　A. Because he’s found the secret of success from it.
