"The First 20 Hours: How to Learn Anything...Fast" is a book written by Josh Kaufman, the same author of "The Personal MBA". The book is focused on providing readers with a framework for rapid skill acquisition.

Kaufman argues that the traditional idea of mastering a skill or becoming an expert after 10,000 hours of practice is not necessarily accurate. Instead, he suggests that by focusing on the right kind of practice and using deliberate practice methods, one can acquire a skill and achieve a level of proficiency in just 20 hours.

The book is divided into three parts. The first part introduces the concept of rapid skill acquisition and provides an overview of the learning process. The second part focuses on the practical application of the principles discussed in the first part. It provides a step-by-step guide for learning any new skill, from playing a musical instrument to programming. The third part focuses on how to maintain and continue to improve the newly acquired skill.

Kaufman provides practical advice on how to set achievable goals, overcome procrastination, break down complex skills into smaller parts, and utilize effective learning techniques such as spaced repetition, deliberate practice, and feedback.

Overall, "The First 20 Hours" is a useful book for anyone who wants to learn a new skill quickly and efficiently. It offers a practical framework and actionable advice for rapid skill acquisition.
