Maybe, or maybe I became used to and ossified in bad strategies. I hope not, but I think I have learned that learning has to be intentional. Meaning for me, writing stuff down, trying to find out other solutions to the same problem rather than just going with whatever my first idea is, etc.
Just doing something for 10 years doesn't make you an expert.
I think it does, just not in the things your measuring.
Sitting on a couch for 10 years will make you an expert. Not an expert in sitting on couches in general but an expert in sitting on your couch during the period you were there.
Pretty sure I got worst at it. 10 years later and now my back hurts.
I like this sentiment. A Wittgenstein collection called “Philosophical Grammar” contains a lot of these kinds of thoughts.
