Without much thinking, I picked up Demian by Hermann Hesse which is so famous that nearly everybody knows it. Frankly speaking, when I was 9, I once attempted to read this book. But it was so difficult that I couldn`t understand. I was too young to consider about things like life and human being at that time. But now I can understand this book more fully. I picked up the book in a casual way, but it became the most precious book I`d ever read. Although I made up my mind to do my Mathematics work as soon as I finished reading, but I just couldn`t. That -I mean, the Book- thing was constantly talking to my mind. `Mathematics is just a tool. You have to live a real life. That`s the thing that people really have to concern! Everything is wrong!` And I had to agree. The most important thing you have to study seems to be ourselves. Therefore I comfortably dipped into thoughts.
