correlation vs. causation. the relationship between the observations is critical here and often misapplied.it's not so much that the 10K hours caused mastery. it's that often times, those w/ mastery of said craft/skill have also at a higher rate that one would observe randomly acrrued said estimated hours.it's a function of natural talent, instruction, and application of those over a long period of time.basically,it's not that X causes Z (x=10k hours, z = mastery), it's much more likely that some other factor or factors, W (talent/aptitude ) and Y (instruction/disciplined practice and application) work with X to cause Z.it's also almost certainly non linear in relationship. likely you'd see a scatter plot w/ a line of best fit showing exponential decay, the more and more advance towards master you get, the less and less you improve w/ the same amount of extra hours.still averaged out it's likely about 3 hours a day over a decade would yield favorable results, so long as the practice/application is guided and appropriate, and that you have the talent and natural skill to allow that level of achievement. Nature cannot fire a gun that isn't loaded.still most will see big gains if they just keep at it over 8-10 years, consistently, hours in and hours out.
-- it's ok that I am not a world famous concert pianist? lol.
So I guess that means that in spite of the fact that I am at more like 100k hours if you add it all up-- it's ok that I am not a world famous concert pianist? lol.
While I know the 10,000 hour to mastery rule is not accepted by everyone, I'm going to go with that as a goal.How do I distribute those hours? How much time on exercises? Learning new pieces? Theory study?
