This goes for you not sharing all your personal stuff, but really this tip applies to what someone might share with you. Instead, if someone talks about money with you, be sure you're respectful.
We recognized that we both (Me & My Wife) had made really good and some really not so good money choices in our past and that neither was perfect. So when we talk about money, we never judge!
At the end of the day, remember it is always OK to agree to disagree! You should learn to agree to disagree when you're talking about money with others! Either way, encourage others for taking control of their financial future!
