Well I'm about to start learning the guitar and I've played many instruments in the past (piano, clarinet, baritone saxophone and bass guitar) and I was just wondering what your motivation was to play?
My current motivation is that I want to start a psychobilly/rockabilly band and since I can't afford an upright bass, I'll learn guitar. I'd also eventually like to be a rhythm guitarist for a thrash metal band.
As for why I want to be a musician: I just love music. I never plan on it being a full time thing, that is left for being a therapist and college professor, but I'd like to form a band and just play and then eventually record stuff and play live shows on weekends and during the summer. I'm definitly not in it for the money and I really wouldn't care if it was a losing money deal, as long as it wasn't a lot of money.
So why do you play your instrument and why would you want to be a musician?
