A lot of people say you ought to treat your writing like a job. Regular start time, daily routines, and the discipline to write even when you don’t feel like it. A lot of fairly successful authors say it too.
On the face of it, sure, it sounds like a fine idea. The problem is… why the fuck would I be doing this if it felt like work? For me, even when it’s work it needs to feel mostly like play. I don’t like following a rigid schedule, and I don’t like planning out my day more than I absolutely have to.
