Have you spent some time browsing job listings (literally any job listings), and noting things that look interesting? Even if they aren't tax related?
Just because you've spent your time so far as a tax accountant, doesn't mean you need to do that forever.
If you do want to stay in the tax/accounting arena, have you thought about starting your own business? is there something you can add to the industry that you haven't seen, or haven't seen done well?
