My Ninjutsu sensei constantly stressed the significance of recording one's progress. The journal, he said, serves as a repository of the art's fundamentals; the basics we must periodically come back to if we are to move forward. It provides a record of what we have been taught, and of what we have done. It reminds us of the eight times we have fallen, and the nine times we have gotten back up. How true! Today, I give my students the same advice. They would never consider pursuing higher educational learning—for earning a livelihood—without ever taking notes. How then can they do less when learning a martial art? No, it's not for earning your livelihood … but it's for saving your life.
