PITCH

Context

I read this during a week in Ibiza in the summer of 2025 — a deliberately unstructured week that I had set aside for reading and thinking away from the usual pace of work. I had been thinking harder about how ideas move between people. Not just whether they are good ideas, but whether they land the way they are intended to. This was the first book I picked up that week, and it set the tone for everything that followed.

What Stuck

The central challenge the book surfaces is the gap between familiarity and clarity. When you understand something well, it is easy to assume that understanding is visible to others. Fontaine pushes back on that directly. The discipline here is not about knowing what you mean — it is about structuring the experience of understanding for someone who does not yet share your frame.

That forced a shift in how I was thinking about presentations and proposals. The question changed from "does this cover everything?" to "does this take someone somewhere?" Those are significantly different tests, and most things fail the second one even when they pass the first.

Application

I found myself sketching things out while reading — not to produce anything finished, but to test whether ideas held up when externalised. Writing and drawing exposed where the coherence I assumed was actually ambiguity I had been carrying around without noticing.

That habit has stayed with me. Before a significant presentation or proposal now, I try to sketch the structure in a way that someone else could follow cold, before I have had a chance to talk them into it.

Reflection

What the book does well is make the invisible workload of communication explicit. It is easy to underestimate how much effort goes into making something feel effortless to the person receiving it. This book makes that effort feel worth doing properly, rather than something to minimise in the name of speed.
