I used to work with a lot of accountants (and lawyers, who's partnership structures are very similar).
What do you want to do? That's the big question to nail down.
Think about three bucks of skills:
What *can* you do?
What are you *really good* at?
What do you enjoy doing?
What type of work gets the most bucket #2 and #3 activities while minimizing the stuff that only goes in #1 for you.
Do you enjoy sales/business development? That's a requirement if you go the partner route. It's also where the most money is in your world. Otherwise you're just selling your skill set by the hour and there's a cap on your earnings. That's okay, but if you're just going to sell your time by the hour, you want to maximize the gap between what you make and what you spend.
You are also underpaid, probably some combination of the prestige that comes with a big firm, crappy sponsorship internally, and the carrot they dangle at you to pay you in the future. I've been in that culture, it sucked not to get paid really well until I was 33 or 34....then when I got paid really well, the money didn't offset the shitty culture.
You get one jump out of a Big 4, if you do it you get to balance maximizing quality of life and maximizing earnings. Maybe the answer is a smaller firm, maybe the answer is an in-house accounting job, maybe the answer is an internal government job. Hope to see you responses
