Open your wallet and take out three dollars. Now, go to a public trashcan (where you won’t be tempted to dig it out). Look into the trashcan; inhale the sweet scent of rotting food, receipts, and stale beer. Stare at the trash – doesn’t it look so pretty? Now hold your fist with the three dollars in it over the trashcan, and let go. Can you do it? I bet you can’t (or if you can, you don’t want to).
Interestingly, many of us do just this without realizing it.
