Extraordinary is boring. If one wants to draw as good as Michelangelo Buonarroti, or play the alto sax technically as well as Charlie Parker, one has to put in the hours. Imagine only having one interest? Example: Michelangelo and Charlie practiced or executed their craft incessantly.

"In an interview with Paul Desmond, Parker said that he spent three to four years practicing up to 15 hours a day."

"If people knew how hard I worked to get my mastery, it wouldn’t seem so wonderful at all." ~ Michelangelo

I argue that one is more employable, more accomplished and has more opportunities if one is average, or above average, in five separate disciplines. Has more diverse friendships too.
