Many years ago, a friend of mine expressed concern about my life taking a right angle turn for the better. We'd helped to carry each other through some disasterous stretches in our lives and he was concerned that I wouldn't be able to write songs anymore if I wasn't miserable. An odd concept (and totally untrue, at least for me.) I know that times of great stress can produce masterpieces of art, but do you think that you have to be miserable to be creative? My friend's attitude was that it was unhappiness that produces the pearl of a song, just like a sand grain in an oyster can be the stimulus for the production of a pearl. My friend was afraid that I would be producing oyster stew rather than pearls.
The kind of songs I've written have changed over the years, but I think that's natural. I'd be concerned if I just kept turning out the same stuff. Same thing with my instumental ability. I can't say that it's gotten better, but at least new ways of expressing myself have come with good times.
As I told my friend, if you need to be miserable to be creative, I hope I never write another song.
