Annotation An upbeat, hopeful guide for people who have trouble walking--ranging from those who have difficulty walking more than a few yards to the wheelchair-bound. The freedom that comes from movement is the important thing, Iezzoni contends, whether under one's own volition or with the help of mobility aids (canes, wheelchairs, scooters, etc.).

Roughly one in ten adult Americans find their walking slowed by progressive chronic conditions like arthritis, back problems, heart and lung diseases, and diabetes. In this passionate and deeply informed book, Lisa I. Iezzoni describes the personal experiences of and societal responses to adults whose mobility makes it difficult for them to live as they wish—partly because of physical and emotional conditions and partly because of persisting societal and environmental barriers. Basing her conclusions on personal experience, a wealth of survey data, and extensive interviews with dozens of people from a wide social spectrum, Iezzoni explains who has mobility problems and why; how mobility difficulties affect people's physical comfort, attitudes, daily activities, and relationships with family and friends throughout their communities; strategies for improving mobility; and how the health care system addresses mobility difficulties, providing and financing services and assistive technologies. Iezzoni claims that, although strategies exist to improve mobility, many people do not know where to turn for advice. She addresses the need to inform policymakers about areas where changes will better accommodate people with difficulty walking. This straightforward and engaging narrative clearly demonstrates that improving people's ability to move freely and independently will enhance overall health and quality of life, not only for these persons, but also for society as a whole.

A startup executive and investor draws on expertise developed at the premier venture capital firm Andreessen Horowitz and as an executive at Uber to address how tech’s most successful products have solved the dreaded "cold start problem”—by leveraging network effects to launch and scale toward billions of users. Although software has become easier to build, launching and scaling new products and services remains difficult. Startups face daunting challenges entering the technology ecosystem, including stiff competition, copycats, and ineffective marketing channels. Teams launching new products must consider the advantages of “the network effect,” where a product or service’s value increases as more users engage with it. Apple, Google, Microsoft, and other tech giants utilize network effects, and most tech products incorporate them, whether they’re messaging apps, workplace collaboration tools, or marketplaces. Network effects provide a path for fledgling products to break through, attracting new users through viral growth and word of mouth. Yet most entrepreneurs lack the vocabulary and context to describe them—much less understand the fundamental principles that drive the effect. What exactly are network effects? How do teams create and build them into their products? How do products compete in a market where every player has them? Andrew Chen draws on his experience and on interviews with the CEOs and founding teams of LinkedIn, Twitch, Zoom, Dropbox, Tinder, Uber, Airbnb, and Pinterest to offer unique insights in answering these questions. Chen also provides practical frameworks and principles that can be applied across products and industries. The Cold Start Problem reveals what makes winning networks thrive, why some startups fail to successfully scale, and, most crucially, why products that create and compete using the network effect are vitally important today.
