There are lots of possible goals. Some people are good at achieving some goals. Performance on most goals that are interesting to me is dependent on the decision making ability of the player (e.g. winning at poker vs being tall).
There is some common thread between being an excellent poker player, a supportive friend and a fantastic cook. Even if the inner decision-making workings seem very different in each one, I think that some people have a mindset that lets them find the appropriate decision-making machinery for each task.
To use a metaphor, whilst some people who can play the piano beautifully would not have become beautiful violin players if they had chosen the violin instead of the piano, most people that play the piano and violin beautifully are just good at practising. I think that most instrumentalists could have become good instrumentalists at most other instruments because they are good at practising (although of course, some people do find success in other ways).
Practising is to learning instruments as applied rationality is achieving goals.
