This book is about changing the world, being a rebel and having a go. It's about how we recognise the need for shifts and summon the courage to make those changes, starting at the smallest level and eventually revolutionizing the very way we lead our teams, our companies and our world. I've often had people, in work and in life, tell me it seemed I was trying to change the world. I would get ahead of them and, sometimes, myself with wild ideas, and they'd encourage me to slow down, break it down so they could understand where my brain was headed. This would frustrate me when I was younger, but not so much now. Now I'm proud to think big -- and changing the world seems a great place to start. Hence the title for this book.
