Pick up any new skill in just 20 hours of focused, deliberate practice. In The First 20 Hours, bestselling author Josh Kaufman challenges the popular "10,000-hour rule" by proving that you don't need a lifetime of mastery to become "good enough" at something. While becoming a world-class expert takes thousands of hours, Kaufman demonstrates that the "frustration barrier"-the initial period where you are most likely to quit because you are bad at a new skill-can be broken in just 20 hours.
