Believing that is the first step to a compromise. This principle works for anyone period.
Just think everyone should consider the possibility that no one really needs the head of R&D. For good intelligence agencies, the guy who does low level IT will do nicely thank you very much.
No one, man or woman, grows closer to being a 10 as they age. So if you work for some of these critical companies and your perfect man or woman shows up, you should be on your guard.
TBH if I was higher up the chain of command, I'd actually give less fucks. If I have a mortgage I cannot afford to lose job or money so I'm on guard because I'm one failed marriage away from homelessness. But if I have ten million dollars to my name, and a Chinese spy shows up then what exactly do I have to lose? If the company kicks me out then good riddance, I can already retire to perfect comfort and nobody can take away the memory of spending a year with a 10/10 partner.
