帮忙翻译一下这段话..哈难懂的额.谢谢哈..
此段出现在一篇以管理情绪为主题的文章中..
The goal is to find the one that works best for you and to use it again and again until your anger management strategy becomes a habit.A common strategy students can begin to try are things like self-talk where you say calming phrases to yourself such as "keep cool," "don't worry about it," and "it will be all right." Other anger management tips include counting backwards from ten at a steady pace and, as always, walking away from the situation that is making you mad.No matter what kind of anger management strategy you choose, it should help turn your bad temper into one that helps you deal with anger in a healthy way!
