Deciding on jobs

I have always been interesting in doing something that involved fashion for example a fashion magazine editor.
However, im not too interested in doing the writing part of it and want to avoid any writing in the future as I struggle at it and I’m not good.
There is of course the issue with money if I’ll be able to live comfortably.
So I have considered scratching that out and becoming an accountant.
I have no idea what to do and am currently picking alevels but don’t know which ones.
Any ideas??

For fashion design/photography/writing, you need no qualifications to do.
For accounting, you typically need to pass 3 A Levels in any subjects + 5 decent GCSEs to do the pickiest professional qualification. If you don't have this, there are always ways around this.
In terms of degrees:
Fashion design and photography degrees do not require specific A Level subjects.
For some accounting degrees (mostly joint finance or economics degrees), you will need A Level Maths. If it's straight accounting, then you don't need A Levels in specific subjects.
Where you don't have required subjects for specific degrees, you would probably want to pick subjects you can get the highest marks in and you are interested in the most.
There is of course the issue with money if I’ll be able to live comfortably.
What does living "comfortably" mean exactly? If it's to own a flat in London, you might have a difficult time getting that with an accounting salary in London. If it's to own a house outside of London, it depends on the house but even then you are likely going to struggle with a £30k salary alone - the rule of thumb is you should only get a mortgage that is at most 5x your annual income (or combined income if you have a partner).
You might want to be specific with this.

Hey im not worried about job requirements only deciding which pathway to take if I should go creative or not since what I would wish to do involves writing which I didn’t realise.
Or
a job involving maths that pays well (which I thought was accounting)

Not all creative areas involve that much writing. For example, you don't write a lot for the following roles:
You would need to be more specific since there is a plethora of these roles.
Degrees that involves "difficult" maths that you typically find in A Level Maths include those in:
In practice though, you only really get jobs in tech (especially if there is a lot of data involved), economics (mostly modelling though), engineering, and finance. Most of the above are more academic subjects i.e. teaching, lecturer.
Even then, a lot of above fields use the computer to do most of the mathematical calculations.
The most mathematical role that I can find from the above that isn't based in academia would be in actuary:

You can become a quant as well, but it's more like using straightforward maths with a little complication and a lot of programming. Most people who go into these roles tend to have a numerical degree e.g. physics, maths, computer science, engineering. You can get a relatively high salary from this, but it would also depend on whether you would also get the job - it's that competitive.

The most mathematical type of engineering is in electrical engineering. See: https://nationalcareers.service.gov.uk/job-profiles/electrical-engineer
You can sometimes get data science roles, but they are apparently dying out according to some people in the field. Instead, I would focus more on being a data analyst or business analyst. The maths involves is relatively straightforward stats with a bit of programming though. See:

If you want to be an economist, I would try to go for something in economics modelling otherwise you're stuck doing straightforward stats. See: https://nationalcareers.service.gov.uk/job-profiles/economist
I you want a mathematical degree, I would make sure you have at least A Level Maths in your arsenal.
