I feel that there's a lot to talk around this topic. I've been kind of isolate too, since a few years ago, I don't think that self-development is the reason but I do feel the same things, like; a lot of ppl have really bad habits (talking too much,criticizing, drinking too much, etc.). But I was taking distance from ppl before I was on this path for various reasons, mostly for my relationship, then become a habit.
The thing is I feel I need to at least talk to ppl, make some friends that I cherish, but I prevent that to happen, I think sometimes is just too scary to be around ppl. I fear ppl will ppl will hurt me with critizicism and stuff. I think i have to work harder to care less about those things bc i really believe that it will be nice to have a few friends i can count with and that bring something nutritive to my life. I have those but only in whatsapp, bc they where my friends when i was a teenage.
This two vids are kind of a warring, one is a study on longevity and shows how ppl can live long when they have ppl to count with. The other is about a study on happiness that shows that the one thing ppl need the most to have a good life is to be sorrounded by high quality friends or something like that.
Sorry for my english btw...
