I don't see anything wrong with not going to uni or getting a trade or anything. But I personally really love learning, it's my passion and hobby, so I feel like there would be a clash if I was with someone who wasn't so interested. And that also goes for someone who is at uni but isn't so interested in the study/learning aspect.
Or am I just a narrow minded person?
(btw I mean this in the context of if I find a long-term partner, I do not currently have one atm)
