Why I have a headache now. I think it is because of my schedule. I should have join a meeting on my personal activity. But I do not want to do it. There are reasons why I do not want. One reason is that I do not want to drive any car. Next is I do not want to lost my free time. Because the meeting is always start delayed. And there are no positive thing(merit) for me. So I do not want to go there anymore.
