"Impromptu"; or, How to Think on Your Feet

The guide invites anyone who wants to sharpen mental agility and speak with confidence to adopt a simple daily habit. By working through brief, unplanned talks, readers discover how clearer thinking translates into clearer expression. The author argues that thoughtful preparation isn’t the only path; consistent, timed practice can forge the same resourcefulness, concentration, and self‑assurance that seasoned speakers display.

The core exercise uses a handful of cards, each bearing a random topic, and a one‑minute timer. After drawing a card, the speaker must launch into a coherent mini‑lecture, aiming to stay on point while allowing the first idea that surfaces to guide the flow. Sample speeches on subjects ranging from Lincoln to salesmanship illustrate what a focused minute can achieve, and the book offers tips for self‑evaluation and progressive improvement.
