How good it takes to become an expert at something, according to Malcolm Gladwell.
This is the most famous claim from Outliers Malcolm Gladwell uses Bill Gates and the Beatles to support his claim that “about 10,000 hours” are required to develop a skill such that you’ll truly become an outlier in that field. The Beatles played 7+ straight hour shows 200+ nights a year for multiple years. This forced them to grow and develop beyond just playing their ‘best songs’. Bill Gates spent his childhood taking advantage of an opportunity to code on a computer for free. Over the course of their early careers they all logged 10,000 hours.
10,000 hours is about 3 hours a day every day for 10 years. Or 5 years of 40 hours/week.
