Ginni Rometty's book "Good Power Leading Positive Change in Our Lives, Work, and World." The book outlines the author's personal and professional journey, detailing her experiences at IBM and the principles of "good power" she learned along the way. Rometty explains how good power can be used to create positive change in our lives, work, and the world through principles like being in service of others, building belief, and stewarding good technology. The book provides a framework for understanding the importance of leading with purpose, authenticity, and inclusivity, and ultimately suggests that good power is not reserved for those in positions of authority but available to all.
