Another good writing tip: replace every “and then” transition with a “and that’s why” or “and despite that” transition
It's valuable to phrase it as "so what" rather than as "why", because people without focus in all fields end up writing only "why the thing being analyzed happened" and not "why this analysis/suggestion/whatever matters". The problem with "why" is that "why"ing the wrong thing ends up just being an extension of the "what". Or at least be up front and clear and say in its entirety "why you need to stop whatever else you are doing right now and listen to me". Writing advice can improve itself by careful attention to writer failure modes.
> And it often flows better if you put it before the what
Indeed. You want to quickly convince the reader to stick around. But often you need to give a little background first, so really it becomes "what, so what, what for real, how, etc"
These are often different. "Why" is often interpreted to mean why the author did it, while "So What?" or "Why Should I Care?" is why the audience should care and continue reading.
If the form is applied thoughtlessly, there's a risk it's gonna feel like the prose equivalent of Corporate Memphis illustrations.

Announcements where personality has been deliberately injected seem to have a habit of beginning with a pithy-but-vague mission statement, immediately followed by “that's why” and then an unwelcome operational detail:
> Here at {company} we know you value {vague nice thing like fairness or something}. That's why we're sunsetting our 64 petaquux widgets, and transitioning all of our customers over to our popular 32 petaquux widgets, in order to enhance your experience.
If you believe what you're saying but you're struggling to articulate it, borrowing a form can help you along, but you really can't manufacture genuinely persuasive writing.
The creators of South Park give the same advice for writing fiction: every two beats in your story should be linked not by an "and" but by a "but" or "therefore".
