As Elvi says, really.
Doesn't matter if you don't use your degree, once you have it, you have it.
A degree done properly, by someone who's engaged in the course should teach you to think.
You won't learn that on an apprenticeship, you'll learn a trade instead. Straight down the lines, not creative. I think you'll realise you've made a huge mistake six months in, because you're more than that.
If you place any value in doing a 'product design' degree then you should continue with it. Is it BA or BSc?
Sorry, but 21 and only a year into your degree? Where'd you waste two years already?
Points made about accidents are very valid, too. Lose the physical ability and you've lost your income. Being trained to think means you should be able to adapt.
I have a very good friend who did the same sort of wrestling with a similar choice two years into his psychology degree, about five years ago. He finished his degree. He then worked through a couple of quirky mechanics jobs and now runs his own garage and loves it.
You've started and made a three year commitment. Shut up, man up and get on with it.
