Suddently I feel that when you do things with a passionate passion these things will finally turn out to be failed. Because a passionate passion always like a brief flame it will go out quickly. On the contrary when you do things with a rational thinking these things will turn out to be successful. And a rational thinking is consist of responsibility and perseverance. The  responsibility for yourself and the perseverance for the things you are doing. To own a rational thinking you need to learn to control your mood first. Be a person with a stead mood  is the first step to do one thing. In stead of being a person with a passionate passion I would rather I have a rational thinking.
