I didn't downvote it, but I also don't agree that a set of rules that amount to "pace yourself to avoid burnout" is a post-hoc rational justification of mysterious otherworldly guidance from the sky.

Since the actual rules from the article are about keeping yourself mentally healthy during the process of writing, the comment is obscure: does it refer to some other set of rules about art? (In which case it's off-topic.) Or is it making the claim that you could work in blocks of multiple hours and never socialise with other writers and see the same results? (In which case, why not clearly state a position so it can be discussed?)
