Best careers with a commerce/business degree?

[unknown]

Hi there!
I finish high school soon and I want to do a commerce/business degree. However i'm indecisive of subjects and all that since i haven't really made my mind of which career i'm heading towards. I've considered chartered accountant but im not sure. And investment banking sounds pretty intense D:

Which career in the business/finance/banking field would earn me the most money?

Thanks in advance guys!
