From the Introduction:
Anger can mess up a kid's life. If you're angry all the time, you might feel exhausted, and your out-of-control emotions can get in the way of your daily life and keep you from enjoying the activities and hobbies you like best. With some hard work, though, you can reduce your anger, which frees up your brain to think positive thoughts and gives you room to enjoy the day-to-day events in your life. Kids tend to be more successful in school once they get their anger under control. Life at home usually gets calmer and more predictable, and friendships grow deeper and more fulfilling.
