I work at KPMG but I want to go to University of Leeds now...(I'm 19)

I'm on the KPMG apprenticeship programme and have realised that it's just not for me. I have an unconditional place at the University of Leeds business school. I know people will think I'm mad for wanting to leave such a reputable firm but I just don't think accountancy and all the finance exams are for me. I think I just took the job because I was just amazed that I'd be working for a large corporate.

I'm thinking of leaving KPMG in July or August and then my degree at the university of Leeds starts in September. I'm really keen to go to university and I wouldn't be applying to KPMG or any other big 4 after my degree as I've now found out its just not for me.

I feel like I need the three years at uni to get a better understanding of what I really want.
Any advice?
