Writing is thinking. In many situations where we are called on to write, what is actually needed is thought.
But in your own mind, your thoughts are still incomplete. The act of writing them down (or, I imagine, in an oral tradition somehow committing to a specific narration) is very important. IMO, when you delegate that to an LLM, you are not really thinking. It's the same as if you explained your ideas to someone (eg in an interview), and then they ghost wrote the work for you.
And then if you want to tell a message with a different tone, again, you must consider differently.
The considering can be strengthened with exercise.
I can't imagine worrying about signaling as I write: what a huge distraction.
The problem is: this type of thinking and writing takes a lot more time and attention.
How much consideration should you put into a message? It's a personal answer, but also one that can be constrained by time.
I was talking about the step before that: what are your ideas?
How do you circle an idea in your own mind: your train of thought, in order to express an idea?
Vocabulary to think, and then if we need to share, we use careful to pick words with the reader in mind.
But just in your own head they lack clarity. I think this can be deceptive to people, it’s a blind spot. How often have you sat down to talk over some disagreement with someone only to find their own thoughts are a jumble of disjointed ideas that don’t make sense?
