They once asked Beatles Paul McCartney if he thought this was true? He replied yes. He said when they became famous they had put in at least 10,000 hours into their music. But he said you need more than that because various other music bands had also put in that amount of time, yet they were not famous. So luck, charisma, talent, being at the right place and at the right time and many other factors are also required to be an International success.

Once we had Master Emin Boztepe for a seminar and he said it was not the number of years you studied martial art but what was important was how many serious hours of correct training went into those hours. By his stories he easily went over the 10,000 hours mark.
Another Master by the name of Kenneth Chng said the reason he was better than us is because to him, we are like and open book. He said he has a mental database of more than 10,000 hands so when he encounters our kind of hands, they are already completely analyzed in his brain. At the first touch he already knows what we are about.
