If you are familiar with Malcolm Gladwell you will likely recall his 10,000 hour “practice makes perfect” theory whereby he asserts that mastery of a skill takes approximately 10,000 hours of doing and practice of said skill.
In this TED Talk video, author Josh Kaufman asserts that while the 10,000 hour theory might apply to athletes, musicians and similarly position individuals it is not what is required to simply pick up a new skill. Rather than 10,000 hours, Kaufman suggests that only 20 hours are needed to learn a new skill and become proficient in it.
In this video, Kaufman breaks down his four-step methodology of learning a new skill in 20 hours. Watch and learn.
