At what point are you just settling vs being far too picky/narrow minded?

Like many of you, the lockdown has meant I’ve had more time on my own than usual. So I’ve been thinking a fair amount, about dating, how I may be limiting myself, and what I potentially want out of dating (while continuing to date via video chat etc). One of the things I’ve never really been sure about is am I being too picky? Am I closing myself off to possibilities by being too narrow with my criteria? Or am I just trying to settle, so to speak? Where’s the line between the two?
