This document summarizes Josh Kaufman's talk on how to learn anything. It notes that with only 20 hours of focused deliberate practice, spread over a month of daily 45 minute sessions, one can learn new skills like a language, drawing, or playing guitar. It breaks learning down into four simple steps: 1) deconstruct the skill into smaller pieces, 2) learn just enough to self-correct during practice, 3) remove barriers to practice, and 4) practice for at least 20 hours. While many claim it takes 10,000 hours to master a skill, research shows moderate performance can be achieved with much less practice time.
