Alcoholics Anonymous helps me keep my ego in check -- "right sized." One result of this is a freedom from interpreting other people's wish to be included as a "threat" to me. To put it another way, other people's "me too" doesn't equal "not you."
The world is a less hostile place from that perspective.
Their abundance is not my lack (because they don't have my stuff -- their stuff has nothing to do with me).
Their success does not diminish me (because their accomplishment or good fortune is not a comment on my abilities or fortunes).
Their faith is not an indictment of my belief -- or doubt, for that matter (even if they think it is).
Whenever I think someone else's anything is a comment upon me, whether overtly or covertly, I've slipped back into an ego based world-view. I'm deeply grateful to Alcoholics Anonymous for giving me the tools to recognize that -- and change it.
Peace.
