"Ask any experienced budget specialist how your family ought to spend its money and he will probably explain that in the bright lexicon of budgeting there is no such phrase as "ought to." The right way, he will say, is to spend as much as you can for things you want most, as little as you can for things you care least about. That's good advice. Your family is different from every other family, so why try to force your spending into someone else's pattern or to mold it to some mythical average? If you prefer to be extravagant in your eating and miserly in your dress, who's to say you mustn't?"
