You know that thing where you ask AI to "write in your voice" and it produces something that technically uses words you might use but sounds like a corporate LinkedIn influencer possessed your keyboard? That's not an AI problem. That's a you problem. (I say this with love. And maybe three drinks. Mostly love.) AI can't follow patterns you haven't documented. When you say "write like me," AI has nothing to work with. So it guesses. Badly. Same structures, same rhythms, same soul-sucking monotony it uses for everyone else. The written equivalent of beige paint. The fix isn't better prompts. It's better inputs. Enter: The Tempo Extraction Exercise Tempo is one of four layers in VAST (Vocabulary, Architecture, Stance, Tempo). It's the most tangible. The layer where you can literally count patterns instead of gesturing vaguely at "vibes" like you're describing a coffee shop's aesthetic. I published the full exercise on Substack, but here's the actionable version for those of you who actually do the work. (All twelve of you. I see you.) THE EXERCISE (20 minutes, 3 parts) Part 1: Sentence Length Distribution (7 min) Grab 3 pieces of your writing. 500+ words each. Count sentences in each bucket: Short: 1-7 words Medium: 8-18 words Long: 19+ words Calculate your rough ratio across all three samples. Mine: 35% short, 50% medium, 15% long. This ratio tells AI what rhythm to target. Without it? Monotonous medium-length sentences that put readers to sleep. (AI defaults to medium the way middle managers default to "let's circle back.") Part 2: Sentence Starters (6 min) List the first word of every sentence in your samples. Look for repetition. Common patterns: 🧉 "I" = first-person dominant 🧉 "But/And/So" = conjunction starters (conversational energy) 🧉 "The" = noun-leading, content-focused 🧉 Verbs = command/imperative style Your top 3-4 starters are your defaults. Document them. Mine lean heavy on conjunction starters. "But" and "And" everywhere. English teachers hate me. Readers don't seem to mind.
