Yep, Mind your own business (MYOB).... tough to do, excellent advise.
Another good one I got the other day at a meeting... "Shut my Mouth".
Both are direct and were new to me.
Both work.
I can't CAUSE addiction
I can't CONTROL addiction
I can't CURE addiction
I think those 3Cs play into MYOB and Shut my mouth.
