At the end of the day, if you don't have a record contract, a studio or a guitar, you can still write songs. You're still an artist. That's something no one can take away.
It's what I do well - I write about things that make people uncomfortable. That's probably the only thing I do better than my peers.
I write a lot from instinct. But as you're writing out of instinct, once you reach a certain level as a songwriter, the craft is always there talking to you in the back of your head...that tells you when it's time to go to the chorus, when it's time to rhyme. Real basic craft... it's second nature.
I want to do some fiction writing, I've had some pretty good luck with short stories, I'd like to do a couple of larger things.
