“I have drawn things since I was six. All that I made before the age of sixty-five is not worth counting. At seventy-three I began to understand the true construction of animals, plants, trees, birds, fishes, and insects. At ninety I will enter into the secret of things. At a hundred and ten, everything--every dot, every dash--will live”

“I have been in love with painting ever since I became conscious of it at the age of six. I drew some pictures I thought fairly good when I was fifty, but really nothing I did before the age of seventy was of any value at all. At seventy-three I have at last caught every aspect of nature–birds, fish, animals, insects, trees, grasses, all. When I am eighty I shall have developed still further and I will really master the secrets of art at ninety. When I reach a hundred my work will be truly sublime and my final goal will be attained around the age of one hundred and ten, when every line and dot I draw will be imbued with life. - from Hokusai’s ‘The Art Crazy Old Man”

“From around the age of six, I had the habit of sketching from life. I became an artist, and from fifty on began producing works that won some reputation, but nothing I did before the age of seventy was worthy of attention. At seventy-three, I began to grasp the structures of birds and beasts, insects and fish, and of the way plants grow. If I go on trying, I will surely understand them still better by the time I am eighty-six, so that by ninety I will have penetrated to their essential nature. At one hundred, I may well have a positively divine understanding of them, while at one hundred and thirty, forty, or more I will have reached the stage where every dot and every stroke I paint will be alive. May Heaven, that grants long life, give me the chance to prove that this is no lie.”

“From the age of 6 I had a mania for drawing the shapes of things. When I was 50 I had published a universe of designs. But all I have done before the the age of 70 is not worth bothering with. At 75 I'll have learned something of the pattern of nature, of animals, of plants, of trees, birds, fish and insects. When I am 80 you will see real progress. At 90 I shall have cut my way deeply into the mystery of life itself. At 100, I shall be a marvelous artist. At 110, everything I create; a dot, a line, will jump to life as never before. To all of you who are going to live as long as I do, I promise to keep my word. I am writing this in my old age. I used to call myself Hokusai, but today I sign my self 'The Old Man Mad About Drawing.”

“Sometimes I lie awake at night thinking about all the dumb things I do every day... If I live to be eighty and I do ten dumb things each day... That would be about two hundred and ninety thousand dumb things... When you add up all the dumb things you do, it's best to use round figures...”

“I counted seventy-three shades of grey in an eight-by-ten room.”
