Just found out it takes 10,000 hours to master any skill. It would take 3 hours of daily practice for 10 years to get to 10,000 hours or mastery.
I believe a lot of the best have 10,000 hours or more. But I mean they would be the best of the best. Although it wouldn't take 10,000 hours to be good at a skill or even great. I believe you can be pretty good at stuff after 100 hours. Anyways here is a video that is interesting on this topic.
