Russ would like to thank his wife, Robin, and his three lovely girls—Ava, Mackenzie, and Annika—for having the patience to put up with him every day.

Sean would like to thank his wife, Nancy, and his daughters—Sophie and Charlotte—for understanding the occasional weekends and late nights that were devoted to writing this book. He would also like to thank his mom and dad for reading to him as a boy and giving him a lifelong love of stories.

Together, Russ and Sean want to thank all of the Bizonians and our new colleagues at LinkedIn who helped with the creation of this book.

They also thank all of the people who shared their insights with them and who were indispensable in shaping the ideas contained in this book.
