"Think Faster, Talk Smarter: How to Speak Successfully When You're Put on the Spot" by Matt Abrahams. It offers strategies for managing anxiety and communicating effectively in spontaneous situations, such as public speaking, meetings, and conversations. The book features a number of practical techniques and frameworks, such as the ADD structure for answering questions and the 4 I's for giving feedback. Abrahams argues that reframing these situations as opportunities for connection and collaboration, rather than threats, can lead to more authentic and impactful communication.
