I just wasn't happy. I didn't go home at night and bang my head against the wall, but I was smoking a lot and drinking a lot and it all sort of caught up with me in this dark night of the soul. I finally thought, before I get too old, I've got to try it, and if it doesn't work out, at least I'm not going to be 65 years old, looking back over my life and saying, 'God, why didn't I at least try?'.
