Forget the "10,000 hour rule"... what if it's possible to learn 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...

His method shows you how to deconstruct complex skills, maximize productive practice, and remove common learning barriers.
