I'm less needy about needing to express myself through acting. I have many different lives outside of this that are extremely fulfilling.
There are some good songs, but not the kind of song-writing that I remember, that I like. Springsteen still does it. Paul Simon, and there are also good writers, but that doesn't dominate the charts.
I always start with characters rather than with a plot, which many critics would say is very obvious from the lack of plot in my films - although I think they do have plots - but the plot is not of primary importance to me, the characters are.
