    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.

    Now the new book More Than Two can help you find your own way. With completely new material and a fresh approach, Franklin Veaux and Eve Rickert wrote More Than Two to expand on and update the themes and ideas in the wildly popular polyamory website morethantwo.com.From partners, authors and practicing polyamorists Franklin Veaux and Eve Rickert comes the long-awaited, wide-ranging resource exploring the often-complex world of living polyamorously. Highlighting the nuances (no, this isn’t swinging), the relationship options (do you suit a V, an N, an open network?), the myths (don’t count on wild orgies and endless sex—but don’t rule them out, either!) and the expectations (communication, transparency and trust are paramount), the authors share not only their hard-won philosophies about polyamory, but also their hurts and embarrassments. More Than Two is entirely without judgment and peppered with a good dose of humor. Franklin and Eve underscore the importance of engaging in ethical polyamory, while gently guiding readers through the thorny issues of jealousy and insecurity. And no, they’re not trying to convert you: they know that polyamory isn’t for everyone. Franklin and Eve simply provide those who might be embarking on this lifestyle, or those who have already begun, with a toolkit to help them make informed decisions and set them on a path to enjoying multiple happy, strong, enriching relationships. More Than Two is the book the polyamory community has been waiting for. And who knows? It may just be the book you didn’t even know you were waiting for.

    The pharaoh's army and navy defeated them, but the victory so weakened Egypt that it soon slid into decline, as did most of the surrounding civilizations. Eric Cline tells the gripping story of how the end was brought about by multiple interconnected failures, ranging from invasion and revolt to earthquakes, drought, famine, and the cutting of international trade routes. Bringing to life a vibrant multicultural world, he draws a sweeping panorama of the empires of the age and shows that it may have been their very interdependence that hastened their dramatic collapse. Now revised and updated, 1177 B.C. sheds light on the complex ties that gave rise to, and eventually destroyed, the flourishing civilizations of the Late Bronze Age--and set the stage for the emergence of classical Greece and, ultimately, our world today.
