If I was hearing the phrase mind your own business for the first time w/o any associations I would think it meant take care off your own affairs.If I was hearing the slogan” Live and let live” for the first time” I would understand that it is a wise and wonderful suggestion to really be alive. I can not mind my business if I am minding yours but the primary suggestion is focus on your self and the slogan primarily suggests to be as alive as you are able. For me that means honest and open sharing with another seeker.
