I assume there must be some kind of genetic thrust. My two grandmothers were very different, but both of them were frustrated musicians.
My style of songwriting is influenced by cinema. I'm a frustrated filmmaker. A fan once said to me, 'Girl, you make me see pictures in my head!' and I took that as a great compliment. That's exactly my intention.
At the point where I'm trying to force something and it's not happening, and I'm getting frustrated with, say, writing a poem, I can go and pick up the brushes and start painting. At the point where the painting seems to not be going anywhere, I go and pick up the guitar.
