It's not just the 10,000 hours, it's learning it very young.
I am an ex-professional ballet dancer, and one of the things I always find interesting is that any experienced ballet dancer can instantly tell who trained as a child and who didn't solely by how they stand (literally not even moving) at the barre. But the thing is, children with only a few years of training under their belt will often show this good form, while I have literally never seen someone who started as an adult, even dedicated adults who take class 4-5 times a week, get rid of that "I started as an adult" posture.
As an example, I was actually quite impressed at how Natalie Portman really managed to "look the part" in her role as a ballerina in Black Swan. Still, she wasn't fooling anyone with training - even with just a simple port de bras (raising of an arm), you could easily tell she wasn't a dancer.
I'm not in the least surprised by that. Bones in children are softer and more malleable, they don't harden up until 16 or so. (That's why young athletes should stick to more reps and lighter weights until 16.)
I've tried emulating those movements, and just look like Bullwinkle.
My partner's also a dance, and this is what's always come across from her, too - that you can tell a dancer from a glance in an instant, even on the street. I have a little bit of an eye for it but only by virtue of being around that environment.
(also: ex-pro ballet to HN? Can't imagine there's much crossover in that Venn!)
> Natalie Portman...you could easily tell she wasn't a dancer.
Which is interesting, because from what I can tell she studied ballet from a young age, which potentially puts a hole in your theory. Unless you're only taking about professional dancers who started young versus professional dancers who started late, rather than any (i.e. non-professional) dancer.
funny, surfing is like this too
I used to think this was true in skateboarding but eventually I found exceptions.
4-5 times / week is not a lot on its own.
You need like 20-25 hours / week. That’s how many actual hours a lot of us kids were spending, at least skateboarding.
If we take the 10,000 hour figure literally, at 20 hours/week, you get good in 9 years, which kind of fits when kids get good.
Almost zero adults I know can (or are willing to) spend 20 hours/wk on a physical hobby.
It doesn’t mean you shouldn’t learn something new, but you gotta be a little strategic.
