Hi again Ricky,
In order to avoid doing something else I did a quick google on 10k repetitions for learning.
Well the story starts in 1993 when Professor Anders Ericsson published a paper on achieving excellence through deliberate practice or study. He suggested 20 hours a week, 50 weeks per year over 10 years could if properly structured make you an expert. This was taken up later by populist writer Malcolm Gladwell in his book “Outliers” as the 10,000 hour rule. Much to the annoyance of Ericsson he did not place much emphasis on the bit about directed study, measurement of progress, feedback and appraisal.
Sports specialists have latched onto to 10k rule. Certainly the best ones follow Ericsson’s findings with measurements, analysis and feedback. Timelines and both positive and negative rewards are included. That is a type of carrot and stick approach.
Some have opted for the 10 k repetition, goal kicking in football for example.
So my original 10k hours statement was correct but 10 k repetitions can be an alternative. ie 10 k hours of study, 10 k repetitions for physical activity. Neither is a golden bullet. They are indicators as to what is required for some levels of knowledge and for some activities. Natural talent, special physical attributes, superior intelligence etc can totally change the achievement rate.
The bottom line is that lots of practice is always required. It also needs to be structured. Review and assessment is necessary so your achievement or lack of it is plain. This helps in self motivation.
