Focused on a simple principle and designed to bolster writers’ confidence and skills, writing coach at Harvard Business School Mark Rennella offers practical advice for students and budding writers—with the goal of leveling the playing field between beginners and those with more experience. After a 30-year career as a writer, instructor, and editor, Mark Rennella has crafted a battle-tested method to help students and young professionals who want to improve their writing: the One-Idea Rule, anchored on the assertion that every component of a successful piece of writing should express only one idea. With The One-Idea Rule, writers embarking on their adult lives and professional journeys will have a reliable methodology they can easily remember and count on for all of their writing tasks, as well as increased confidence about the cogency of their writing and its potential for impact in the public sphere. Most advice about writing looks like a long laundry list of dos and don’ts. For those already accomplished as writers, these lists can be a helpful addition to an already-developed communication style. But for teens starting college and young professionals entering the workforce, it can be challenging to wield such complex advice to tackle increasingly demanding writing assignments. The One-Idea Rule is a writing primer aligned and empathetic with any young writer's needs.

This book traces the progression of cosmopolitanism from the private experience of a group of artists and intellectuals who lived and worked in Boston between 1865 and 1915 to finished works of monumental art that shaped public space.

Entrepreneurs, Managers and Leaders examines the role that business leaders play in shaping industries and how the evolving context of industries shapes leaders in turn. This co-evolutionary process of leadership and industry development is told through the story of the American airline industry across the 20th century. Entrepreneurs, who explored a variety of different airline concepts in search of a viable business model, dominate the industry’s early history. As the industry evolved, a new breed of managers emerged who built a dominant business model that enabled their companies to grow dramatically. Later, after the industry matured, leaders took center-stage as agents of change to rebuild and revitalize the industry. The lessons to be drawn from the experience of the airlines and their executives will be of interest to business leaders in industries across a wide spectrum. Despite the indelible mark that many individuals have made on their industry, writers on industry evolution-concerning the airlines or any other industry-have rarely factored in leadership as a way of explaining or understanding that evolution. Entrepreneurs, Managers and Leaders seeks to paint a fuller picture of the interdependent relationship between the actions of leaders, the context of their times, and the evolution of an industry.

Game Changers gives readers a horizontal and vertical view of the wide reach of innovation over time and its impact on the lives of individuals and societies. Innovation has shaped human history in decisive ways. From light bulbs to lasers, from plumbing to water purification, innovation has helped human beings deal with change, cope with major problems and to achieve what had once seemed either impossible or even unthinkable. Today, innovation is increasing in importance to human society because so much of our well- being depends on it. In a future that will be largely shaped by increasing demands on finite natural resources, innovation will be the key to being able to do more with less. As a result, the well-known mantra from many companies to do work that is "better, faster and cheaper" will become decreasingly connected to the idea of return on investment; instead, the improvements brought about by innovation will be increasingly associated with truly sustainable (i.e., enduring) economic development and, most importantly, sustainable competitive advantage. We can choose the wrong path of continuing with old economic habits in a new era. Game Changers remind us that change for the better is indeed possible and essential, but it (like the innovations reviewed in this book) will take focused effort and hard work.
