I'd like to choose a niche that corresponds to the industry I want to work in: Insurance/Financial Services. Problem is, I know very little about this industry and I don't have the money to study for a FS qualification. If start a site on let's say remortage insurance or asset management insurance and it ends up being full of misinformed / amateur opinion, I am afraid it will look awful if in the future I show it to a potential employer. Is this a concrete risk? Shall I just stick to something I know about like football or music, but won't serve my future career / professional development?
I wanna specify that I am actually interested in this niche, my knowledge is just very amateur. There's Financial Qualifications I could get of course, but they're way too expensive for me.
PS: I'll narrow it down of course, I'm aware it's a very broad niche
