Jerry was a manager in a restaurant.He was always in a good mood(脾气）and always had something positive to say.This really made me curious, so one day I asked him,"It's hard to be a positive person all of the time.How do you do it?'' Jerry replied ,"Each morning I wake up and sayto myself,"Jerry, you can choose to be in a good mood or a bad mood," and I choose to be in a good mood. Life is all about what you choose.And what you choose leads your life."Several years later,I heard that Jerry left the back door open one morning and was robbed(抢劫）.While trying to stop the thief ,he was shot. I went to see him in the hospital.When I asked him how he was,he replied,"If I were any better,I'd be twins." "Weren't you scared when you were in danger?"I asked."Yes. The doctors kept telling me that I was going to be fine, but in their eyes,I read."He's dead."I knew I needed to take action." "What did you do?" "Well.there was a big nurse asking me if I was allergic(过敏的）to anything."Yes,'I replied ."Bullets(子弹）!Everyone laughed and I told them: I am choosing to live. Operate on me as if I am alive." Jerry lived thanks to the great doctors ,and also because of his amazing attitude(态度）.Attitude ,after all ,is everything.
