Am I passionate enough to do a maths degree?

At university level, Maths and Physics are very similar in that Physics is largely just applied maths.

I’m also interested in physics but more the theoretical side so if I decide I want to go into that, I can easily do that as a masters

So I’ve been debating about what course to apply for, for uni for a while, and I think I’ve decided on a maths degree on the basis that I quite like maths, and I’m also interested in physics but more the theoretical side so if I decide I want to go into that, I can easily do that as a masters, and also maths gives me a lot of options. I’ve always enjoyed maths and liked problem - solving but recently I’ve met a lot of people who want to do maths too and they all seemed a lot more passionate about it than me? I’ve done courses and read books and watched some videos outside of a-levels, but I don’t feel like I have the same ‘drive’ I suppose as they do, I feel like I used to when I was doing GCSEs a little more, but maybe it was just because it was really easy. I do find the a level relatively easy too though, but also consequently quite boring so maybe that’s the issue. It’s just I’m looking at applying to Cambridge and compared to other people also applying there I feel quite inadequate, and that they have done more maths and are a lot better at it, if anyone has any advice on the matter that would be appreciated, thanks
