As I said, minding your own business needs a lot of humbleness, politeness and respect for the other human being. It needs an understanding on your part, that the other person is an individual with his particular set of choices, and he/she is free to follow his/her choices. You need to understand that you are not always right and playing Miss Know-It-All or Mr. Know-It-All will take you nowhere and will in fact, take the other people away from you. So, the mantra is "Live and Let Live". If you think you are the goddess of fashion or a finance guru, keep it to yourself, because you know what, the world doesn't care and nobody has the time to listen to you bragging and boasting. Also, you may not always find a humble listener. So, beware of witty comebacks before you open your mouth.

All my growing years, I have come across various people who lack the quality of humbleness. And I have noted that these people are somehow obsessed with boasting and also hint low self-esteem. Otherwise, why do you need to be so loud when making a point so that the whole of the room notices you and not just the person you are talking to. Or why do you need to say sentences like, 'why are you wearing this dress' or 'I got a job, pays big bucks, blah blah', when all the other person is doing is playing friends with you.
