Want to be really really good? Like Bob Dylan, Bill Gates, Warren Buffet etc.? You have to do what you are doing for 10,000 hours.
I like Malcom Gladwell – he is iconoclastic, eccentric and intellectual. So it caught my eye. So how many is 10,000 hours in days and years?
Quite a bit – 4 hours per day, which is a fair bit to focus attention on exclusively, for 5 days a week, works out to 960 hours per year, which would be 10.41 years.
