I think I'm a songwriter. I grab an instrument to make my body a song, but I'm not a player as such, maybe a little more on guitar, but certainly not piano.
My success has been something I've worked a long time at and it's been a gradual process. I compare it to the idea of someone losing a lot of weight over a period of a few years. You don't really notice the weight loss overall but if you compare photos from then and now there's a big difference.
I think it starts to feel really redundant when you start to do something the same way over and over again. I don't think it's good to become so dependent on a certain writing process.
