I teach in a school, and am constantly reminded that frugality is becoming a lost virtue. This article reminded me of the extent to which that quality formerly reached.
In my own life, I waste money all the time - most of us do. We buy snacks we don't need (and add to our weight problems), splurge on toys and entertainment, pay too much because we're in too big a hurry to bargain-hunt, buy convenience foods, and incur charges for doing all that on credit.
It's sloppy money management. And, although I do make an effort to watch my spending, I'm guilty of wasting money in many ways.
When I hear people talk about how broke they are, and how "someone" needs to give them money, I do question their need, if they have cable, ready-made snacks, junk food, and cell phones in their house.
BTW, all of the above are LUXURIES.
