The way a friend of mines describes JJ is that he has creative ADD, he gets all hopped up on an idea, starts working on it for a while but then starts to lose interest as another idea hits, he then leaves the current project for others to finish while he moves on to his next project. You then rinse and repeat as he starts but never finishes any number of projects or, in the case of movies, loses steam and creative interest. It really makes a lot of sense when you look at just how many projects JJ seems to have going at any one time, at any one time he seems to be working on or at least overseeing 2 or 3 different TV shows, writing/directing a movie, and doing pre-production work for another movie.
