“Although time is the critical factor in attaining Mastery and this intuitive feel, the time we are talking about is not neutral or simply quantitative. An hour of Einstein’s thinking at the age of sixteen does not equal an hour spent by an average high school student working on a problem in physics. It is not a matter of studying a subject for twenty years, and then emerging as a Master. The time that leads to mastery is dependent on the intensity of our focus.”
