THE FIRST 20 HOURS is a book by Josh Kaufman that offers a systematic approach to rapid skill acquisition: how to learn any new skill as quickly as possible. His method shows you how to deconstruct complex skills, maximize productive practice, and remove common learning barriers.
Having learned how to ski, ride a motorcycle, sing, play the guitar, skateboard, oil paint, remodel a house, build a computer, etc. independently I new his claim is possible. I never monitored the time I put in.
I decided to learn the LAMR stack in 20 hours… and I did.
