Not all stress is bad for you．Some kinds of stress can help you get things do better，like when you are running towards the finishing line or when you are being asked to give a speech to your class．Stress sometimes can help push you to make full preparation for a test．However，too much stress can result in anger，depression and other related problems，which we need to take serious．
There are many things in our life what might cause stress------having too much homework，taking a difficult test，and having economic problems．
It's impossible to live in a life completely free of stress，so you should learn to deal with stress．The best way reduce stress is to have a balanced life．If you get enough sleep，eat properly，take more exercise and have enough fun time，you'll probable feel less stressed．
