The Master said, at 15 I set my heart upon learning

At 30, I had planted my feet firm upon the ground.

At 40, I no longer suffered from perplexities.

At 50, I knew what were the biddings of heaven.

At 60, I heard them with docile ears.

At 70, I could follow the dictates of my own heart;
for what I desired no longer overstepped the boundaries of right.

-- Confucious

Keep walking, because walking is life.

-- Masaaki Hatsumi
