I don't think you quite got the point of my post. I wasn't saying that people should do Maths although they hate it so they can earn megabucks as an investment banker.
Rather, a quantitative element can be found in many fields which aren't traditionally associated with mathematics.
Furthermore, maths teaching at schools is often dry and boring. It can be very different with better, more focused teaching in university, when applied to a particular subject.
Teenagers don't usually know the ins and out of particular careers in detail, who they truly are and what they want from life. So IMO it's too early to write off 'anything involving Maths'. 'do what you love' well that implies that 'what you love' is something static and never changing. Untrue. A-levels are too shallow to be a good signal as to preferences.
Like I said, I too hated it and as a teenager never imagined that I'd work in a technical role involving mathematical thinking. But it was taught in a completely different way in university, I saw it in a different light, in a way I had never thought of before. Instead of something cold, separate and contradictory. It bolstered my strengths in Humanities subjects and gave me an edge over others.
A lot of people also change careers after finding out that their impressions of certain careers were different from the reality, and maths can help there too. And in 2024 so many professions are set to be disrupted by technology, layoffs, etc. Again, not talking about wanting to be the fabled 'high earner', but basic security like a home, food and work/life balance.
A little bit of discomfort at 17 is a small price to pay, in my opinion, for your future.
