I've known a few well adjusted individuals who finished their education early.

You would tend not to notice except in conversation when you add things up and realise they are unusually accomplished.

Personally I think it's weird making people learn in lock step by age rather than allowing them to progress at their natural rate.

There are a few different underlying assumptions there when you think about it, eg that a) people of the same age have equal "maturity" b) socialising with people older than you is harmful (or less beneficial) compared to socialising with people the same age as you c) socialisation mainly happens in an institutional context d) the purpose of higher education is socialisation as much as learning.

Any or several of those ^ can be false for a particular student. Of course the institution and other students matter too in terms of outcome.

"Pushing" and validation chasing are bad tho, with you on that one.
