Someone once explained it to me.
You are NOT an accountant (or whatever else it is that you do…). First and foremost you are an eved Hashem. Therefore, you are an Eved Hashem who WORKS IN ACCOUNTING. So I guess if anyone asks you, just say, I work in [fill in whatever it is you do that gives you parnassa] rather than I am a [whatever you do]…
With that said, I am an Eved Hashem, and I find extreme fulfillment as an educator, i.e. I teach for a living… and I LOVE it!
