A really good picture looks as if it's happened at once. It's an immediate image. For my own work, when a picture looks labored and overworked, and you can read in it as well - she did this and then she did that; there is something in it that has not got to do with beautiful art to me. And I usually throw these out, though I think very often it takes ten of those over-labored efforts to produce one really beautiful wrist motion that is synchronized with your head and heart, and you have it, and therefore it looks as if it were born in a minute.
