Do you have any problems in your life and don’t know how to be happy ? If so, you will find Being a Happy Teenager written by an Australian writer Andrew Matthews.

In his book, Matthews tells us how to have a happy life and answers the questions of teenagers. There are many subjects, such as parents and friends, and the book says we should stop being angry and should forgive (宽恕). The book tells us some useful ways, such as how to understand better what you learned. Many teenagers think that happiness comes from a good exam result or praise(表扬) from other people. But you can still be happy when there are no such “good” things.

Success comes from a good attitude (态度). If you learn from problems, you will have success in the future. Some school students have problems, such as being too tall or too short. But Matthews tells us that happiness comes from thinking in a positive (积极的) way. If you are tall, you can get a better view(视线)when you see a film; if you are short, your clothes and shoes take less room in your bedroom! This is Matthews’ most important lesson: “ You choose to be happy!”
