For a long time I never considered this question since making up tunes and singing along to them – relying totally on serendipity – was a childish habit I developed as soon as I was big enough to hold a guitar. This was long before I asked why anyone did anything. Only later in my early teens did I slowly become aware that writing songs could be a medium for something called “self-expression” – but I think I saw it as equivalent to others who might choose sport or some other recreation or hobby. Only much later, when writing and playing became my sole source of income, did I concern myself with the purpose of the songs – the “why?” of the songs. I no longer wrote songs for their own sake – songwriting became a means to an end. Then later again, when I quit touring and playing for a living, I wondered what purpose there would be in continuing to write songs since the means no longer had an end. Habit? That wasn’t enough. So I decided to stop.
