I have to admit that I only write potential lyrics, not songs, but I also end up having several pots on the stove. I thought that this was just my lack of focus but I might be in the shower or at the shops and a few words come in to my head, then anything else I was working on is suspended. However, I am very new to this so I don't really have an end in sight if that makes sense, so it feels ok to write down as much as possible. Good to know more experienced folks are operating in a similar way - maybe its the way of the creative spirit
