10,000 hours rule

The 10,000 hours rule suggests that achieving mastery in a skill typically requires about 10,000 hours of focused practice. Developed by Malcolm Gladwell, the idea is that consistent, deliberate effort over a long period is necessary to become highly skilled in areas like music, sports, or other crafts. It emphasizes that talent alone isn't enough; dedicated practice is key. While not a strict formula, it highlights the importance of perseverance, effort, and time investment in reaching expert levels of performance.
