When you study now, you will know yourself well. That is, you will ask yourself what is the best and most interesting subject to study. What is the most interesting? When you suddenly awaken in the middle of the night, ask yourself what is the most interesting. Is music interesting, or there is something else? There is this original nature in you. Your taste buds are also like that. Some people like to eat fish while others do not. Some people like certain kinds of vegetables, others like kimchi. Everyone is different, aren't they? If you have a certain nature that likes a certain kind of food, even if you did not eat it for one or two days you would not suddenly come to dislike that food. If you like something, you would normally continue to like it for the rest of your life. Did you know that? We display the same kind of nature when we study. We like to study the subjects that we enjoy the most. So what kind of subject will you study? You have to think deeply about it. As you are in your adolescence, I suppose you all like pop music. It may sound good, but you cannot say that you will always like a particular song. We have to consider the value of things-what we mean when we say something is good. Centering on the standard of what is good in childhood, youth, adulthood, old age, past, present and the future, you can determine what is valuable and what is a fitting and interesting subject for you. Then you should focus your concentration on studying that subject.

How should we study? Studying is for the purpose of pursuing the goals you have set. If you like science, then you should study about science. You cannot study all the subjects with the same intensity. After you have specialized in science then you can widen your knowledge horizontally as needed. You can broaden your horizons. In the world today, you certainly need to have a vocational subject. Whatever subject you choose, you will then study centered upon that subject. If it is science, you have to know about the history of science. You have to know the history of scientific development and about the scientists who made it possible. Next, you need to know what level modern scientists are at. You need to know where you stand in relation to them. With science advancing from the past through the present, are you standing in the position to advance or fall back? If you are falling back, stop doing so: you must be in the position to go forward. It can be concluded that if you want to be in a position to advance, you must study harder than those in the past and in the present time. You must study hard. If you compare with how people have done things in the past and in the present time, you might say that someone scored 80 but you got 75. If we look centering on modern scientists, someone scored 100 while you scored 60-we compare in this way. To reach 100 from 60, you must get 40 more, and it takes effort to accomplish this. Through that way, you must go up to the highest position. Do you follow? That is something substantial. Do you understand? You have to make that kind of effort. If you go the way of the spearhead of the world, making such efforts in each field, you will be in the position of leading the best people from each of those fields.

So you must quickly decide what to focus on. After deciding, you must make a comparison with all the great people of the past, present and future. When you make effort to move everything beyond their level, these people will stand behind you. You must therefore become the best people from each sphere, becoming those who can lead all people.(100-118)
