I see absolutely no reason to begin work knowing exactly what is going to happen. I want to be surprised during the creative process and also long after the event. This can only be achieved by working quickly, intuitively and in the moment, avoiding reliable techniques and knowing when to move on to something else.
Paint is a material that can convey much more than just visual information, when understood and used with feeling. Like playing music, it is not just about playing the right notes in the right order. Painting without feeling becomes an exercise in pure technique and ultimately means nothing.
