I couldn't find the original quote, but if I can paraphrase it:
Spend two pence less than you make and you'll be content, maybe even happy. Spend two pence more than you make and you'll be miserable.
Spend two pence less than you make and you'll be content, maybe even happy. Spend two pence more than you make and you'll be miserable.
"Annual income twenty pounds, annual expenditure nineteen pounds nineteen and six, result happiness. Annual income twenty pounds, annual expenditure twenty pounds ought and six, result misery."
