Being Happy: How Not to Love Stuff →
ROI (return on investment) is a useful concept to help you minimize the number of stuff in your life. When you buy something, think of it as an investment. The question is: can you get good return on your investment? The return here isn’t financial. It’s the overall value you get from the stuff. Will it make your life considerably better? Will it give you long-term happiness? Invest your money only on things that give you good ROI.
