If there's a 100 people working in a corporation, it means 10% of them will do 50% of the work, while the remaining 90% will do the other 50%. This is why there's usually a few insanely prolific people in any given field while the rest fight for scraps. You have a productive scientist like Nikola Tesla who makes breakthrough discoveries all throughout his life, businessmen like Steve Jobs that continually push boundaries in terms of technology, a film director like Stephen Spielberg who makes successful movies for decades, musicians that make a shitload of hits like the Aerosmith while the rest can barely squeeze in a one hit wonder.
