The Pareto Principle (roughly 80% of consequences come from 20% of causes: a.k.a. the 80/20 rule) is a mental model that I use for my day-to-day work. But I wonder, is it applicable to the creative aspect of writing?

For example, for the craft of writing, I firmly believe it applies: If I devote 10 hours to writing, most of my quality work will come from about 2 hours of it.

But what about a writing project’s key creative insight?

The one thing that makes a writing project special?

The flash of insight that brings everything together?

The special moment?

The—and I use this word with reservation—paradigm shift?

Perhaps there is a Pareto Principle on steroids for discovering these elements—not an 80/20 rule, but a 99/1 rule, or even a 99.9/0.1 rule?

Can this rare aspect of creativity be modeled by a ratio rule?

I doubt it.
