At age 75, Katsuhika Hokusai timelined his artistic quest: "At the age of 73, I finally apprehended something of the true quality of birds, animals, insects, fishes, and of the vital nature of grasses and trees.  Therefore at 80, I shall have made some progress, at 90 I shall have penetrated even further into the deeper meaning of things, at 100 I shall have become truly marvelous, and at 110, each dot, each line shall surely possess a life of its own."  Vincent Van Gogh achieved Hokusai's dream at the age of 37.  (Michael R.
