Most shows drift because their promise is fuzzy. This ten-minute workshop guides solo hosts through a repeatable method to create a one-sentence Show Thesis plus three ready-to-use derivatives. You get a compact 3-question distillation (who you serve, the change you deliver, how you deliver it), a novelty: the 3-word stress test (can the thesis be reduced to three memorable words), and a short listener role-play to validate clarity. The episode includes before/after thesis examples in true crime, business, wellness, and narrative storytelling, a two-minute rewrite drill, and a simple A/B test protocol with a benchmark (aim for a 10-25% lift in trailer CTA click-through or other short-term metric). Hosts receive guardrails to avoid over-narrowing, language that feels corporate, and a flexible outline for conversational delivery. The episode closes with a micro-challenge and a link to download a one-page worksheet and templates at podcastresources.example/thesiskit.
