Pros

I’m comfortable here — which frankly, is wonderful. Based on my specific role (which is a bit unique) I have great work/life balance and great pay. But requires setting boundaries and being firm.

Cons

It’s an agency, so it can be stressful and demanding at times. Upward mobility depends primarily on willingness to do new business.
