In IGCSE, choose one between Human Biology and Business Studies

I want to discuss with you based on my ambivalent decisions. Now, I am still choosing subjects for the IGCSE o-level. Human Biology Vs Business Studies

Actually, I feel like I am interested in Human Biology, and Business studies is like a boring subject when I read those textbooks. But, I think Business will help me in my future career, and conversely, Human Bio can't. So, which subject should I take? Can you give me your opinion, please?

Ps: I don't have any specific career which I want to do in my future. But, I want to be a writer at my heart. The thing is that I don't know which major is the best for me in the university if I wanna be an author.

Pls, give me any suggestions! Thank You so much!!!
