Yes, But How Do You Know? is an invitation to think philosophically through the use of sceptical ideas. Hetherington challenges our complacency and asks us to reconsider what we think we know. How much can we discover about our surroundings? What sort of beings are we? Can we trust our own reasoning? Is science all it is cracked up to be? Can we acquire knowledge of God? Are even the contents of our own minds transparent? In inviting, lucid prose, Hetherington addresses these questions and more, using scepticism to illuminate many perennial philosophical puzzles.

A practical three-step method for saying no in any situation—without losing the deal or the relationship, from the author of Possible and Getting Past No “In this wonderful book, William Ury teaches us how to say No—with grace and effect—so that we might create an even better Yes.”—Jim Collins, author of Good to Great In The Power of a Positive No, William Ury of Harvard Law School’s Program on Negotiation teaches you how to take the next step toward getting what you want. It all begins with the most powerful and perhaps most important word in any situation: No. But saying the wrong kind of No can destroy what we value and alienate others. That’s why saying No the right way—to people at work, at home, and in our communities—is crucial. You’ll learn how to: • Assert your own interests while respecting the other side’s • Use power effectively • Defuse the other side’s attack, manipulation, and guilt tactics • Reduce stress and anxiety • Develop healthier relationships • Stand up for yourself without stepping on the other person’s toes In today’s world of high stress and limitless choices, the pressure to give in and say Yes grows greater every day, producing overload and overwork, expanding e-mail and eroding ethics. Never has No been more needed. And with The Power of a Positive No, we can learn how to use No to profoundly transform our lives by enabling us to say Yes to what counts—our own needs, values, and priorities.

Forget the 10,000 hour rule— what if it’s possible to learn the basics of any new skill in 20 hours or less? Take a moment to consider how many things you want to learn to do. What’s on your list? What’s holding you back from getting started? Are you worried about the time and effort it takes to acquire new skills—time you don’t have and effort you can’t spare? Research suggests it takes 10,000 hours to develop a new skill. In this nonstop world when will you ever find that much time and energy? To make matters worse, the early hours of prac­ticing something new are always the most frustrating. That’s why it’s difficult to learn how to speak a new language, play an instrument, hit a golf ball, or shoot great photos. It’s so much easier to watch TV or surf the web . . . In The First 20 Hours, Josh Kaufman offers a systematic approach to rapid skill acquisition— how to learn any new skill as quickly as possible. His method shows you how to deconstruct com­plex skills, maximize productive practice, and remove common learning barriers. By complet­ing just 20 hours of focused, deliberate practice you’ll go from knowing absolutely nothing to performing noticeably well. Kaufman personally field-tested the meth­ods in this book. You’ll have a front row seat as he develops a personal yoga practice, writes his own web-based computer programs, teaches himself to touch type on a nonstandard key­board, explores the oldest and most complex board game in history, picks up the ukulele, and learns how to windsurf. Here are a few of the sim­ple techniques he teaches: Define your target performance level: Fig­ure out what your desired level of skill looks like, what you’re trying to achieve, and what you’ll be able to do when you’re done. The more specific, the better. Deconstruct the skill: Most of the things we think of as skills are actually bundles of smaller subskills. If you break down the subcompo­nents, it’s easier to figure out which ones are most important and practice those first. Eliminate barriers to practice: Removing common distractions and unnecessary effort makes it much easier to sit down and focus on deliberate practice. Create fast feedback loops: Getting accu­rate, real-time information about how well you’re performing during practice makes it much easier to improve. Whether you want to paint a portrait, launch a start-up, fly an airplane, or juggle flaming chain­saws, The First 20 Hours will help you pick up the basics of any skill in record time . . . and have more fun along the way.
