I see my creative process as a two-part thing: there’s the idea and the actual creation process itself. My habit is to always keep “ideas” in stock. I have a notebook (music notation paper) that I carry with me all the time and there’s also a folder on my PC with snippets of audio. So I try to keep a log of “ideas” to be used as a spark for a creative process. Sometimes using an idea that’s 15+ years old (and I can’t quite recall where that came from) takes me to unexpected places. I guess this habit made me avoid the “Blank Page Syndrome” for ages…
