If you measure life in terms of "hours expended earning money", then wasting money is equivalent to wasting hours of life. Now imagine every time you come home from the grocery store and offload, say, 6 bags of delicious groceries at roughly $25 each, some gal walks in out of the blue, grabs one bag, stomps it to bits, throws it down the garbage disposal, then leaves without explanation, without even taking anything for herself. Just comes in and throws $25 of your life away, not to mention the time it took you to plan and shop for those groceries and bring them home. Senseless, pointless waste.
Upwards and onward!
