In Mother Teresa, CEO, Ruma Bose and Lou Faust explain how a humble ministry founded by a diminutive nun in 1948 became an organization that today operates in over one hundred countries with four thousand workers and that has managed over a billion dollars in capital.

How did Mother Teresa's Missionaries of Charity become one of the world's most influential organizations? Bose and Faust argue that Mother Teresa "applied her ethical principles and values to work she was passionate about"—and that the practices employed by this unassuming but powerful nun can be utilized by each one of us.

In the early 1990s, Bose served Mother Teresa as a volunteer for the Missionaries of Charity. Ever since, she's reflected on lessons she learned there, and has now distilled them into eight principles for "running an organization, a single project, or your everyday life."
