personally, I think it is false to think about skills as linear model, it is more inverse exponential model a like. In another words, what I am trying to is that; if you have sustained environment, discipline, and some luck, it is straight forward to become worst of the best. How fast you get there will depend to some extent of advice and guidance, but one has ask self; does he want to become in shortest time worst of the best or become worst of the best no matter what.
