It's intuitively obvious that if you're a relatively healthy person, and grind at a goal exclusively with no other desire, you'll eventually be at least good at it if not spectacular.
Applying that to something that you're personally interested in makes sense - but the idea that you want to be a "top performer" in some wanky capitalist game so that you can have a load of numbers and buy some fancy toys at the cost of deleting your empathy is totally absurd to most people.
That's _why_ it's abnormal, because it's a shit way to live and most people don't want it. Hell, I thought I wanted it for the longest time, eventually I grew out of it and I'm glad I did and that I'm still able to make up for lost time.
As long as you can convince yourself that you know it's possible - you don't need to like, actually do it. Go and enjoy yourself and those around you, we're only here once.
