Hitendra Wadhwa

Wadhwa teaches at Columbia Business School and runs a leadership institute alongside it. Inner Mastery, Outer Impact draws on Gandhi, Lincoln, Mandela and Malala to argue that the useful question is not what leaders do but what state they are acting from, and it sets out five inner cores he says can be trained. He came to the subject from mathematics and management consulting rather than from psychology, which shows in how the book is structured.
