The emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world-class expert – in anything. In study after study of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, master criminals, and what have you, this number comes up again and again.

I've been working at my job for 14 years (X 2000 hrs/yr = 28,000)
I must be a world class expert.

I think maybe you also have to have a certain knack for something, to begin with, before that 10,000 hrs can start ...
otherwise all us old guys would be world class experts smile

I do not work here, but the benefits are still awesome
