I want to try to keep optimist. I found a interesting article. The title is "Looking on the Bright Side Might Help You Live Longer". According to the article, Optimism is connected with healthier behaviors and healthier ways of dealing with difficult situations. Optimists tend to take better care of themselves by exercising, eating healthy foods and getting enough sleep. Doing These things is so simple. But it's hard for me. I sometimes stay up late at the night. I eat junk food once in a while. And I occasionally get angry to my family and friends. I want to quit these things. So I'll keep that in mind．
