The NYT has a great article, 'Fortune’s Fools: Why the Rich Go Broke', that is well worth your time to read. And Foreman does a pretty good job of getting to the heart of wealth:
Mr. Foreman, who stared down financial collapse as an adult despite a troubled, impoverished childhood, said he knew real wealth when he saw it. “If you’re confident, you’re wealthy,” he says. “I’ve seen guys who work on a ship channel and they get to a certain point and they’re confident. You can look in their faces, they’re longshoremen, and they have this confidence about them.”
He says he can spot a longshoreman who has enough equity in his home and enough money in the bank to feel secure, and that some people, no matter how much money they have, never get there. “I’ve seen a lot of guys with millions and they don’t have any confidence,” he says. “So they’re not wealthy.”
And Warren Buffett understands, too:
Questioned in 1991 about the reasons rich people hit the skids, the multibillionaire investor Warren E. Buffett told an audience at Notre Dame that debt and alcohol were ever-present culprits in financial demise. “I’ve seen more people fail because of liquor and leverage — leverage being borrowed money,” he said, according to a transcript of his comments. “You really don’t need leverage in this world much. If you’re smart, you’re going to make a lot of money without borrowing.
“I’ve never borrowed a significant amount of money in my life. Never,” he added. “Never will. I’ve got no interest in it. The other reason is I never thought I would be way happier when I had 2X instead of X.”
We'll never have true contentment and proper spiritual focus unless we understand that. The hard part is doing it.
