"At least as far back as Agamemnon and Achilles on the beaches of Troy, relationships have had the power to create or to destroy enormous amounts of capital—human, social, intellectual, and economic.

[...] If relationships can have such a decisive impact on the success, even survival, of leaders and their firms, why do so many of us give them such short shrift? The answer lies in the outdated belief system that governs how we conduct business. Among the many beliefs that make up this system, four are killers. This manifesto is a call for us to shift to a new set."
