A glass of water is delicious after you get all of a sweat. It's so because you want to drink it. If other one compels you to drink it, it is not so. When you work hard and get tired, sleeping is the most important pleasure. In such a day, you can have a deep sleep. But there are the days when you can't do so. At that time, though you might say to youself, "I have to sleep! I must sleep when I can't sleep!", it comes to be more difficult for you to sleep. Modern people live within the habit in their mind that they have to do something. I think that human mind gets binded more strongly by such feelings as "must work!", "must study!", "must hurry!" and "must meet someone!". Nowadays those feelings may generate modern disease so-called stress. Your work can't last for just a day if you consider the work as compeling. On the other hand, you don't feel fatigued if you want to do a thing and do it. The reason why children seem to be tireless is that they do the things they want. I think that the modern problem remains because the importance of such children's mind have not been enough to be recognized yet. I think that people always don't forget remembering the mind of about three-years-old child and recovering the human's nature mind without confusing the uncertain look of the civilization. The earth maybe catch a modern disease.

Nowadays the nature is being destroyed rapidly. As well as it, in fact humanity also may be being destroyed under the name of education. I can't help hoping with everyone all over the world to seek for the intrinsic nature figure of human.
