This app helps you break down a new skill into 20 hours of structured practice. It's inspired by the book The First 20 Hours by Josh Kaufman. Results may vary depending on the skill and your practice.
The 20-Hour Theory, popularized by Josh Kaufman in the book The First 20 Hours, argues that it isn't necessary to spend thousands of hours learning something new — as suggested by the famous "10,000-Hour Rule" — but rather about 20 hours of deliberate practice to reach a basic functional level in virtually any skill. The central idea is that by dedicating oneself in a focused and structured way for a relatively short period, it is possible to overcome the initial difficulty phase and perform the skill satisfactorily, even if mastery is still far away.
