In his book, “Outliers: The Story of Success”, Malcolm Gladwell wrote that it takes 10,000 hours to master any task.
while, disputed, realistically, this rule means to say the mastery of a skill:
- takes time,
- requires practice/repetition,
- required focus, and
- must is earned through effort
Please, understand that other concepts are applicable and that all skills and knowledge are perishable and permeable.
