Susan Cain’s book ‘Quiet’ has had a big influence on me. It’s a manifesto in support of the world’s introverts and how to make the most of their talents. You get a sense of the book from her inspiring TED talk – here. I spend much of my working life facilitating workshops, standing in front of people and telling them what to do. Despite this, I’m an introvert. (really, it’s true!) I have a lot of sympathy for introverts who attend workshops.
