Million Dollar Weekend

USA Today Bestseller National Bestseller "Like going to business school and therapy all in one book." —James Clear, New York Times Bestselling Author, Atomic Habits Once a barista in a small cafe making $6.50 an hour, Andrew Wilkinson built a business valued at over a billion dollars by the time he was 36—and yet, his path to success was anything but a straight line. In Never Enough, Wilkinson pulls back the curtain on the lives of the ultra-rich, sharing insights into building a successful business that has been called a “Berkshire Hathaway, but for internetcompanies,” and a surprising first-person account of what it’s actually like to become a billionaire. Never Enough features both the lessons Wilkinson has learned as well as the many mistakes made on the road to wealth—some of which cost him money, happiness, and important relationships. Taking a “no secrets” approach to stories the wealthy rarely reveal, Wilkinson is unwaveringly honest about some of the unexpected downsides of money: its toxic effect on personal relationships, how the lifestyles of the rich and famous aren’t all they’re cracked up to be, and how competition with peers leaves everyone—even billionaires—feeling like they never have enough. In this book, you’ll discover: A candid glimpse into the lives of the super-rich and what truly matters beyond money Insights on building a successful business from the ground up Lessons learned from the mistakes made on the journey to his fortune The surprising realities of life as a billionaire and the challenges that come with extreme wealth In this rare and deeply honest account, Wilkinson examines his journey to nine zeros, what came after that pinnacled number, and the essential things money can’t buy.

Never Enough

Revised and Updated, Featuring a New Case Study How do successful companies create products people can’t put down? Why do some products capture widespread attention while others flop? What makes us engage with certain products out of sheer habit? Is there a pattern underlying how technologies hook us? Nir Eyal answers these questions (and many more) by explaining the Hook Model—a four-step process embedded into the products of many successful companies to subtly encourage customer behavior. Through consecutive “hook cycles,” these products reach their ultimate goal of bringing users back again and again without depending on costly advertising or aggressive messaging. Hooked is based on Eyal’s years of research, consulting, and practical experience. He wrote the book he wished had been available to him as a start-up founder—not abstract theory, but a how-to guide for building better products. Hooked is written for product managers, designers, marketers, start-up founders, and anyone who seeks to understand how products influence our behavior. Eyal provides readers with: • Practical insights to create user habits that stick. • Actionable steps for building products people love. • Fascinating examples from the iPhone to Twitter, Pinterest to the Bible App, and many other habit-forming products.
