According to Ross, how long does it take to master any field through heavy labor?

The assertion that it takes about 15 years to master any field through heavy labor stems from the concept of the "10,000-hour rule," popularized by Malcolm Gladwell, which suggests that extensive practice is necessary to achieve expertise. Ross's interpretation aligns with the idea that mastery requires not just time but also dedicated effort and persistent practice. Over roughly 15 years, individuals can accumulate a breadth of knowledge, experience, and skill, which is essential for becoming proficient in a complex field.

This timeframe encompasses various stages of learning, including initial exposure, skill development, repeated application, and eventual mastery. The journey to expertise involves not merely clocking hours but engaging actively and thoughtfully in the field, facing challenges, and refining one’s abilities through experience. Therefore, the notion that mastering a discipline can take about 15 years emphasizes the commitment and resilience needed to truly excel.
