From his years as a litigator, Rabois learned that all the magic of persuasive writing is in the first paragraph. Getting the first three sentences right could take a week or two of walking around thinking, but once the framing clicked he could write 30 pages in two days. The lesson generalises to any persuasive communication and even to prompting AI: the framing is the leverage point, not the volume.
Origin
Rabois's own method from his first ~4.5 years as a law clerk and litigator, applied to briefs; he extends it to AI prompting (short examples, edit, re-prompt) in the AI-era discussion.
Core principles
- 01The first paragraph carries almost all the persuasive weight — nailing it dramatically raises your win rate
- 02Framing the opening is the hard, high-leverage work; the bulk of the writing is comparatively easy once framing is set
- 03Invest time out of proportion to length in the opening — weeks on three sentences, days on thirty pages
- 04Breakthroughs on framing often arrive away from the desk — in the shower or on a run
- 05The same principle applies to AI writing: many short examples, edit, and re-prompt beat asking for long output
How to run it
- 1
Treat the opening as the whole battle
Accept that the first three sentences (or first paragraph) determine whether you persuade your audience. Prioritise them above everything else in the piece.
Pro tip Getting the opening right measurably raised Rabois's odds of winning a case and convincing the judge.
- 2
Spend disproportionate time on framing
Allocate a large share of your available time to figuring out how to frame the opening — even a week or more of a three-week project spent just on the first three sentences.
Pro tip Walk around and think rather than forcing words onto the page; framing breakthroughs often come in the shower or mid-run.
Watch out Don't rush to draft the body before the framing has clicked — you'll waste the effort.

Power through once the frame clicks
After you've cracked the opening framing, write the rest quickly — the body flows because the hard decision is already made.
Pro tip Rabois could write 30 pages in about two days once the first three sentences were set.

Apply the same discipline to AI writing
For AI-generated writing, don't ask for long output. Give many short examples, then edit and re-prompt — because short prompts yield markedly better quality than page-to-chapter requests.
Pro tip Rabois attributes weak long-form AI writing partly to token rationing — short requests get significantly better quality.
In the wild
Given three weeks to write a brief, Rabois would spend the first week or more walking around the office working out how to nail the first three sentences. Once he had them, he could write 30 pages in about two days — but the framing sometimes only came to him in the shower or on a run.
→ Nailing the opening dramatically increased his odds of winning the case and persuading the judge.
Common mistakes
Drafting the body before framing the opening
Starting on the bulk of the writing before the first three sentences are right wastes effort, because the framing decision is what makes the rest cohere and persuade.
Asking AI for long-form output
Requesting a page-to-chapter piece from an LLM yields significantly worse quality than short prompts; the better method is many short examples, edited and re-prompted.
Is it for you?
Best for
Anyone writing to persuade — pitches, briefs, essays, prompts — who wants to concentrate effort where it actually moves the outcome
Not ideal for
Purely informational or reference writing where persuasive framing isn't the goal and speed matters more than the opening
From the transcript
“The hardest part of writing a brief all all the art I mean all the magic was the first paragraph.”
“If I could write that first paragraph really well the chance I would win the case and convince the judge would go through the roof.”
“Once I figured out how I wanted to frame those first three sentences, I could write 30 pages in like 2 days.”
“the writing it right now what works best is short many short examples”
