We all know that change is hard. It's unsettling, it's time-consuming, and all too often we give up at the first sign of a setback. But why do we insist on seeing the obstacles rather than the goal? This is the question that Chip and Dan Heath tackle in their book. They argue that we need only understand how our minds function in order to unlock shortcuts to switches in behaviour. They illustrate their ideas with scientific studies and remarkable real-life turnarounds.
