....that basically said there's no such thing as innate genius; that people who are brilliant at something, whether it be painting or music or engineering or fashion, are brilliant simply because of the focus they give it and the amount of attention they devote to it
That's an interesting idea.
I'll have to think about it for a while, however the flipside might explain a fellow I knew who was an absolutely brilliant technologist but the very worst dresser ever - according to any standard one might want to pick.
The flipside is that, rather than 10,000 hours, my friend's total time spent thinking about fashion was not likely more than 10 minutes. Choices were more about what he needed to wear, not whether the items went together.... "Gee, I need to wear a tie today. Oh, here's one" ...often resulting in the ghastliest combinations imaginable.
