I could not resist posting this Robert Crumb video in response to various conversations today dealing with 'ideas and concepts'. In the first moments of the film the interviewer asks Crumb what he is trying to get at with his work. Crumb responds with music to my ears::: 'Jesus, uuuh I don't know'. While Crumb's manner of speaking is difficult to follow at times, his message might be refreshing to some. It is ok to work with no sense of direction---you will know where you are when you get there.
If you want to watch the whole video, I might recommend the 2:47 mark---POWERFUL SHAPELY LEGS
