So I've been trying to figure out what exactly the creative process is and I haven't been able to nail it down. The best explanations I have found described recombining ideas and looking at things from different angles, whatever that means. These sources then talk about letting the ideas "germinate." I kind of get what they are going for but it's really not driving into the heart of what the creative process is. I need a more advanced and complete explanation of it. Any books that can give me this?
