I want to work in the Hospitality field! But..?

First, I am 15.

I want to work in the Hospitality field but I'm afraid my parents won't like it. I'm pretty sure they are going to criticize me on why I would want to serve others and deal with rude customers when I could be sitting in an office and making money at the same time.

Honestly, I can ignore their criticism for me being in this field; but it would still be a bother to me. If that makes any sense ? Please understand T__T

I particularly want to work where there's travel, meeting new people and cultures, serving, not a boring 9-5 shift, not in a boring office box, and where I can see people happy because that makes me happy. I'm interested in jobs that are physical. I don't to work in jobs that do lots of thinking. Something like an Accountant. My mom considers me to have a career in it but to me, it would feel like going to school everyday for the rest of my life. Just SITTING THERE and look at numbers all day long. No.

I don't know.. I wanted to be an Industrial Engineer but my math and science aren't promising.

People say majoring in Accounting is a promising career but I'm not interested in it. I would consider majoring in it if I have no way out.

People say majoring in Hospitality and tourism management aren't worth it in this economy but I am interested in it.

Someone, please help? Anybody majored in Hotel management/Hospitality related majors; please tell me how your experience was?
