Have you ever had problems in your life? Have you ever wondered how to be happy? If so, you will find the book Being a Happy Teenager (write) by an Australian writer Andrew Matthews (use).
In his book, Matthews tells us how to have a happy life and (answer) the questions of teenagers.
There are many subjects, such as parents and friends, and the book says we should stop behaving (angry) and should forgive. The book tells us some useful skills, such as how to put you have learned into pictures of your mind to make your memory better.
Many teenagers think that (happy) comes from a good exam result or praise from other people. But you can still be happy when there are no such "good" things. Success comes from good attitude. If you learn from problems, you (have) success in the future.
Some school students have problems, such as (be) too tall or too short. But Matthews tells us that we should think about things a positive way. This is Matthews, most important lesson: You choose to be happy!
