It’s about action.In this practical guide, Mayer reveals eleven provocative principles that flip conventional leadership wisdom: “Leadership is worthless . . . but leading is priceless.” “Power is worthless . . . but influence is priceless.” “Success is worthless . . . but failure is priceless.” Through gripping stories from the Pentagon’s smoking corridors, NFL sidelines, and Ukrainian hospitals, he shows how real leaders emerge not from corner offices but from moments of crisis when someone must step up and act.Whether readers are managing a team, raising a family, or facing a crossroads, Mayer’s hard-won insights will transform how readers think about influence, teamwork, and making decisions under pressure. This isn’t theoretical leadership.
