I was reading a new short book called Do the Work on the subway this morning, and it contained this little gem.
"I ask myself agin of a project - what is this damn thing about ? Keep refining your understanding of the theme, keep narrowing it down.. It is the thorniest nut of any creative endeavor.. It is pure hell to answer this question. More books, movies, businesses get screwed up ( or rather, screw themselves up) due to failure to confront and solve this issue than for any other reason."
The book itself is a little rah-rah, but is a whole new model of publishing as well from domino project.com.
