For me Freeowl hit the nail in the head.
I carry around many insecurities with me, too old, fat, not funny enough, not smart enough, not this not that enough. When I tune into these feelings it is then that I find it difficult to be around other people.
We are now living in a society where judgement of others is prevalent. In magazines, social media, TV. IMO it makes us question who we are too much.
Not sure where I was going with this.. I'm going to blame PAWS lol.
But in answer to your question I don't think there are many who naturally fall inline and feel comfortable around others. For me the key has been not focusing on those insecurities. I can only be me and mostly I believe I am enough. Falling inline for me is always trying to do what I believe is fair and just. Do as ye will, but do no harm.
Just my 2c worth
