Drawing on the simple four-colour system that made Surrounded by Idiots a global bestseller, Erikson shows how understanding your boss’s behavioural tendencies as well as your own will lead to a more harmonious and productive workplace. He also sets out what characterises an exemplary leader type and how you can adapt your behaviour to model it. Because there are two sides to every coin, Erikson also looks at employees themselves and why some colleagues frequently underachieve and what you can do to change this.

But Tesla’s success was far from guaranteed. Founded in the 2000s, the company was built on an audacious vision.

Tesla would undergo a hellish fifteen years, beset by rivals—pressured by investors, hobbled by whistleblowers. Musk often found himself in the public’s crosshairs, threatening to bring down the company he had helped build.
