However, ( 7 ) Mozart produced in his early years is not considered to be particularly outstanding. He didn't produce his first true masterpiece* until he was 21; pretty s young to be sure, but Mozart ( 1 ) already been composing for years by this time. 10 The figure of 10,000 hours has been suggested as the amount (1 of serious practice or study needed to truly master a skill. That is nearly two hours a day, every day, for 14 years. Natural ability is, of course, an important factor in success, but even someone as talented as Mozart couldn't become a "great" composer until he had put in* 10,000 hours of hard work.

Although that seems like a ot of hours, most people spend about a third of them asleep. Take way all the hours we "lose" moving from place to place, eating, etc., well as the time spent at work or school, and the amount of free me we have starts to look quite limited.
