It takes 20 hours to learn a new skill – 10,000 hours to master a.k.a become an Olympian.
Deconstruct the skill: Break down the parts and find the most important things to practice first. If you were learning to play a musical instrument, for example, knowing just a few chords gives you access to tons of songs. If you want to learn a new language, learn the most common 2,000 words and you’ll have 80% text coverage.
Self-correct: Use reference materials to learn enough that you know when you make a mistake so you can correct yourself.
Remove barriers to learning: Identify and remove anything that distracts you from focusing on the skill you want to learn.
Practice at least 20 hours.
