You write a scene, and it works or it doesn't. It's immediate.
Writing is a necessary thing for me, just to keep myself level. It has beneficial effects on my life.
There are times when I think I can sing it better, but usually I find that I can't.
Songwriting, I have to take myself away from everybody to do. It's an unsightly act.
My muse is my wife. It's not some vague thing that flutters around the astrosphere or wherever it is. Sometimes as a songwriter you need something to hang a song on, to give it some kind of presence and form. For me, Susie is that.
After a while, you just don't do things you don't wanna do - that's the great freedom you get, the older you get. You learn what to do and what not to do, and what will be a waste of time and what won't be a waste of time.
