Make sure to be honest with yourself, about if that's really what you want to do with your life - to make music. It takes a commitment - a tremendous, thick-skinned commitment of being the first one to get there and the last one to leave, doing what you want to do even if you have to work twice as hard as anybody else ever did.
I don't have any real process. Some people in Nashville go in like an assembly line. They're able to go and write. My son runs a publishing company. He has writers that come down. They get together in a room with the people that actually make appointments, and write - which is great. I can't do that very well.
