The Three Platforms at a Glance

Compressed from Lessons 35. Same 3 signals (Stop → Stay → React), three different shapes.

Start-here rule Publish first where the barrier is lowest: LinkedIn (pure writing) → Instagram Reels (screen + text) → YouTube (voiceover, then face). Same idea can be repackaged across all three — one thought, three posts.

Signals are read in order everywhere: a weak Stop means Stay and React are never tested. Fix the earliest weak signal first.
