I think you nailed it near the end where you remark on the absence of any sort of organized "body" waiting to vet you. It's just individuals. Perhaps individuals with strong connections between themselves, but individuals nonetheless. And importantly, individuals who were once at the same threshold that you're now hesitant to cross.
Of course, there are plenty of things that make every one of us different and qualified in separate respects, but I think that sometimes it can be grounding to recall those moments where those differences all but vanish. Moments of commonality if you will.
