Decide on a sector and then do something relevant, take some time to do work experience if you need to
don't stress about it, remember:
1. if you don't enjoy your sector you can get a general graduate role and try and move around, you're not fixed into one career
2. most degrees will have a really wide variety of options job wise
3. no one enjoys every single aspect of your degree so if you choose something with a few modules which aren't for you it doesn't matter
4. you can swap degrees after 1 year
also, you CAN do well without a degree depending on your field... e.g. with youth work you could get into a lower management role in the care sector without a degree
