Pablo Picasso said this quote

“ Everyone wants to understand art. Why not try to understand the song of a bird? Why does one love the night, flowers, everything around one, without trying to understand them? But in the case of a painting people have to understand. If only they would realize above all that an artist works of necessity, that he himself is only a trifling bit of the world, and that no more importance should be attached to him than to plenty of other things which please us in the world, though we can't explain them. People who try to explain pictures are usually barking up the wrong tree. ”
