根据短文内容,回答下列问题。

    Have you ever had 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 useful.

    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 skills, such as how to put what you have learned into

pictures of your mind to make your memory better. Many teenagers think that happiness comes from a good

exam result or praise (赞扬) 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 form thinking in a positive (积极的) way. If you are tall, people notice you and you can get a better view

(视线) at the movie; 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!
