I'm learning slowly to not be as much of a control freak. I can't afford to be all the time, but I'm getting better at communicating. Delegating parts of my vision for other people to execute has made it an easier process for knowing what I want, and what people can handle, and what I should probably save for myself.
You can tell if there's magic in something. When you start it, you want to finish it and you want it to be perfect. If you're not inspired, and you're working hard to pull inspiration from somewhere and make a song something it's not, then it's very contrived, and I don't like to write music that's contrived.
