Currency is in your checking account and in your refrigerator. It layers your body on an almost-autumn evening and it gets you to Point B. Currency is what some people have in spades and others, sometimes, not quite enough. The clout that comes with cash reserves is apparent all around us, but it's time to consider that money doesn't have the market cornered when it comes to currency.
The currencies that don't instantaneously turn what you're craving for into what's in your hand are just as valuable; if you're thinking long term, maybe more.
Faith, hope, love, intelligence, mindfulness, empathy, compassion, kindness, reputation all require effort to acquire and accumulate, too.
So maybe money can't buy happiness. Doesn't mean you can't try a different currency.
