Alas, I think it is far more likely that there is no secret to any of this. Different strokes will arrive at the same place for a lot of people. All the more true for things that are even remotely creative in nature.

Not to say that routine and form can't get results. It is hilarious how much of the current fascination with LLM writing can be summarized by "actually filling out a routine template will satisfy a ton of requirements." People that are surprised with how well some output works, but would have scoffed at filling out a lot of boilerplate in previous technologies.

So, yes, try it. But do not become attached to it. If it works, rejoice in that. But do not count on it always working. If it stops for a time, feel free to leave it for a time.

Absolutely. "One size fits all", doesn't. Doesn't even fit one, all of the time.
