If you like detail and dealing with numbers and money,  are reasonably good at maths, are good at picking up small errors, and can handle computers well (most firms these days use accounting programs like Quickbooks and MYOB, they are actually really easy to use compared to spreadsheets - i did a certificate in Introductory Accounting a few years ago, so i have some knowledge here), then accountancy might be for you.

You can earn a good living at it, if the remuneration for it is anything like NZ's. (My sister is an accountant, so again i have some knowledge in this area.) But be aware there will still be some dealing with clients, when your HR knowledge could come in useful. That's if you go into an accounting firm, or set up on your own, if you join a big company then you'll still have to deal with office politics etc. But perhaps less so than as an HR? It depends, do you feel you would be any good at HR, never mind your being AS, as we can take up all sorts of careers. It depends on what you really WANT to be, what you feel YOUR capabilities are.
