Even though I've been a solid atheist since my moment of awakening in 2002, I have continued to talk about blessings. "My life is blessed." "You are so blessed." "What a blessing!" Benign banter with believers.
I am deciding that the only blessings I want to talk about are those given from person to person. "You are blessing me!" (with some gift of time or object) "He/she is blessing him/her/them!" (in response to some uplifting story).
I am still attached to the idea of luck and being lucky though. Not sure how that fits in. Is luck a useful concept?
