Akira Kurosawa said this quote

In the pre-war era when itinerant home-remedy salesmen still wandered the country, they had a traditional patter for selling a potion that was supposed to be particularly effective in treating burns and cuts. A toad with four legs in front and six behind would be placed in a box with mirrors lining the four walls. The toad, amazed at its own appearance from every angle, would break into an oily sweat. This sweat would be collected and simmered for 3,721 days while being stirred with a willow branch. The result was the marvelous potion.When writing about myself, I feel something like that toad in the box.
