choices and eventualities
Look at what your career path will be for both eventualities. do you think you can climb the management ladder or do you thonk you will stay on the bottom rung? Do you want to climb the management ladder? What kind of technical path forward is in place? Is there room for you on that path?
Have you been in a management position before? Is there an opportuntiy for you to try on the "new shoes" for a bit to see if they fit you? It is all about choices and which ones will be right for you.
