​What are some good business ideas to open for someone who has no experience in business/marketing?

I (21F) have always dreamed of opening a business of my own..but was never sure what to open

I am a makeup artist but I don’t have any clients..my goal right now is to open my own makeup shop but there are so many makeup artists in my country that it’s really difficult to do so, so I just gave up

I also have no idea how business/marketing works, and it doesn’t interest me to study it at college as what if I don’t manage to open my own business and would have spent years studying it for nothing?
