My father-in-law was a very good friend of one of the richest men in Massachusetts, whom he knew and befriended long before he had any money. The guy drove a Ford station wagon and lived in a [neat] three bedroom home in a middleclass neighborhood. He was quietly generous to charities, but skeptical of con artists and four flushers.
You’ll find that most millionaires aren’t showy.
They live in the same neighbourhoods much of their lives, drive beat-up cars.
They aren’t flashy and they really watch their money.
That’s often why they are millionaires. :)
