I had read a book which title is "Ikigai ni tsuite", meaning considering about Life, written by Kamiya Michiko yesterday. I had picked it up at the library in the hospital. Though I know nothing about this book, it looked good, and it's good as it looks. Good reading experience always makes me feel better. Something go down in my stomach and it's comfortable for me. In this book, it is said that psychological movement, like drawing, writing Haiku, playing music instruments, thinking about math, and so on, can often help our lives. The man who want nothing but pleasure of doing itself is the man who truly want and need to study.
