David Hockney…2

 18Art has to move you and design does not, unless it’s a good design for a bus.
The moment you cheat for the sake of beauty, you know you’re an artist.
It is very good advice to believe only what an artist does, rather than what he says about his work.

Once something has outlived its usefulness in one area of life, its purpose for being in existence is no longer the same. The leaf that captures a stream of sunlight, and then transfers its energy to the tree, serves one purpose in the spring and summer, and another completely different one through the fall and winter.
