Meh, it depends, but you're generally right. If you waste your 20s on inane technical achievement and ladder climbing, then you haven't spent time figuring out how to form healthy personal connections, or on the extreme end, you might be a total asshole and nobody's told you because they couldn't care less to burden themselves with someone who only cares about their job. If I didn't have a few different relationship experiences, I wouldn't be in a healthy one now. If you get it right the first time, you're very lucky. So you better start now, otherwise the prospect of starting a family might literally be out of reach within 5 to 10 years, though the marriage thing, if you want that, is always possible.

At the moment, I'm a bit younger than 32, but I almost consider relentless tech grinding to represent a silly sort of immaturity, or at least a bit confusing. As in "You seriously haven't found something else to do with the little spare time you have?", not that I'd say that.

Yeah, I met my now wife at that age.
