Let's go over a few things that your mother's should have taught you...
Don't judge a book by it's cover.
Yes, first impressions last a lifetime and you should always present your best self...BUT...everyone has their own personal style and interests...just because ours may differ from theirs, doesn't make either less valid.
Axiom to book/cover...you are not defined by your possessions.
It is vulgar to discuss money.
Whether it's how much you have or how much you need, it's not for public consumption. Sharing shopping tips or bargains? Fantastic! Have at it! Our friends and family can be our greatest resource when it comes to ideas about home-keeping, style, investments, new products, etc. That said, broadcasting how much you do or don't have in the bank? What will it accomplish? Making others jealous or making others pity you? Nothing good can come of it. Keep it to yourself.
There is a difference between Money and Power.
Just this once, I'll break the rule about talking about money as this is a matter of public record...let's consider a few salaries...just to be clear...
President of the United States: $400,000 per year
Chief Justice, US Supreme Court: $223,500 per year
Tim Allen: $225,000 per episode
Ashton Kutcher (highest paid television actor): $700,000 per episode
Queen of England: £32.1m last year
Prime Minister of the UK: £142,500 per year
I hope this clears up any lessons from Mom on which some people made need a refresher. Feel free to let me know if I've left anything out that bears repeating and/or explanation. I'm here to help.
