John Stezaker describes how Picasso did not look for images, but found them, the distinction here suggesting an openness to sources as they present themselves (noticing?), over a search for what you think you want (looking?);

What he meant was that the searching is more likely to lead you not to find anything, because you don’t really know what you want in the first place, so you have to abandon yourself to a kind of searching which doesn’t predispose you to a very specific conclusion or image. The finding is the key element because that’s the point in which you’ve abandoned yourself from the search, you’ve taken yourself outside the linearity of a particular channel.
