Thomas Stanley wrote The Millionaire Next Door.
He urges us to live below our means and notes that wealthy people (not to be confused with affluence/abundance) are tenacious and hard workers.
Most of the wealthy people in America, he states, are not those who wear large diamond rings, or live in mansions. They are the ones who drive old pick up trucks (like Sam Walton did) and are careful with their money.
