The 10,000-hour rule for mastery is likely incorrect.

“there are so many things we come and doing this podcast that are just fascinating beyond belief including a really good explanation of why the 10,000 hour rule that most people take for granted is essentially an axiom or Dogma ie that you know 10,000 hours of deliberate practice is what is required for mastery and greatness and I David goes into a great explanation of why that's probably completely nonsense which is not to say that deliberate practice is not incredibly important but to break it down to something as simple as ten thousand hours is almost assuredly incorrect”
