"Consider that: •   According to its principle creator, Taiichi Ohno, it took 28 years (1945-1973) to create and install the Toyota Production System, which is maneuver conflict applied to manufacturing. •   It takes roughly 15 years of experience—and recognition as a leader in one’s technical field—to qualify as a susha (development manager) for a new Toyota vehicle.150 •   Studies of people regarded as the top experts in a number of fields suggest that they practice about four hours a day, virtually every day, for 10 years before they achieve a recognized level of mastery.151 •   It takes a minimum of 8 years beyond a bachelor’s degree to train a surgeon (4 years medical school and 4 or more years of residency.) •   It takes four to six years on the average beyond a bachelor’s degree to complete a Ph.D. •   It takes three years or so to earn a black belt (first degree) in the martial arts and four to six years beyond that to earn third degree, assuming you are in good physical condition to begin with. •   It takes a bare minimum of five years military service to qualify for the Special Forces “Green Beret” (minimum rank of corporal / captain with airborne qualification, then a 1-2 year highly rigorous and selective training program.) •   It takes three years to achieve proficiency as a first level leader in an infantry unit—a squad leader.152"
