More about the book...

Change isn’t an easy sell. And, in business, pivoting in a new direction requires teams to work together cooperatively. While a half-hearted agreement to adopt a common goal may get you short-term momentum, if you want to initiate lasting change that creates sustained action, you need to give your audience a reason to believe. You need, as the title of this book suggests, to say what they can’t unhear.

From renowned strategist, author, and speaker Tamsen Webster comes this compact and actionable guide that will get you thinking differently about where change comes from and how to initiate it. By introducing and exploring nine “persuasion proverbs,” Webster highlights the behavioral, cognitive, and psychological principles that underpin lasting change, and offers a powerful alternative to the standard tactics of influence and persuasion. The outlined concepts are easy to remember, simple to implement, and will give you the tools to transform any audience of lukewarm prospects into passionate believers.

If you’re looking to spark change in your audience in a way that has them excited and motivated, that pushes them beyond temporary action, and that makes them feel empowered instead of manipulated, then Say What They Can’t Unhear is the resource you need in your back pocket.
