About the 10,000 Hour Rule

Popularized by Malcolm Gladwell in "Outliers," the 10,000 hour rule suggests that expertise in any field requires roughly 10,000 hours of deliberate practice. In BJJ terms, this roughly correlates with high-level black belt proficiency.

Important: Quality matters more than quantity. 100 hours of focused drilling is worth more than 200 hours of unfocused rolling. Track what you practice, not just how long.
