Agree, this part i have to agree with also what myo said about low profile. Just keep low profile and don't boast, if outside people ask about your property, just say you are renting it from others. Even if you paid in cash for a car or house,
always tell them you got it financed or mortgaged.
Never show off for any reasons, its good to be always prudent and humble even if someone shows off in front of you and flaunts a 150k annual pay, just smile and say he is really good and always stop the missus from blurting out anything she should not say.
It keeps one safe and no one will target you as they think you are poorer than them, in fact they might be happy if you don't visit them as they may be concerned that you may borrow money from them!
One doesn't need to win every battle, as long as the wife, family or close friends know where you stand is good enough. Those who have deep pockets might not necessarily be driving big cars.
You can only really tell who your friends are when you are seen to be "in trouble", false friends and those who have always been boasting about their wealth can easily be caught out. Real friends will stand by you, thats what friends are for.
