When it comes to time-saving tips, I have to admit that I am not an efficient person. The schedule only works when I　am in a "good condition." The thing is that what I know doesn’t always mean what I would do so. Is it difficult to get the point? I think, more or less, people know too many "hows and shoulds," but couldn’t really practice them. I know, I know, it needs all kinds of great characters such as determination, principle, insistence, and so on, and so forth, but I am just a weak-minded person. It’s sad, and I know that well.
