I want to change my boss's mind, but he won't listen. I want to change the way we operate around here, but there are too many obstacles. I want to make some changes in my life, but I'm scared they might not work out. All too often our desire to improve things is undermined by the scepticism of others and by our own caution and fear. In Switch, best-selling authors Chip and Dan Heath delve deep inside the human psyche to explain why this should be so, but they also argue that once we understand how our minds function, there are practical steps we can take to overcome our inbuilt resistance to change. And the results can be extraordinary.
