Accountants' job is to account, where do the money come from and
where it goes, approvals procedures adhered to or not, especially
for non budgetted payments. You need to be meticulous, attend to
details, can be boring, long hours. Unless you do external audit,
you are only dealing with your own company people. It suits you, if
you like desk job, don't want to deal with too many funny
people.
Business (finance) is a totally different study, you run a
business, manage money, take risks, ....
go to the universities and find out what the subjects are all
about, and see what you like and what suit you.
