...............can be found right here. Secrets and formulas are nice, but the unfortunately reality is that happiness is an inside job. Nobody has ever really improved on Lincoln's thought that we are about as happy as we make up our mind to be. Still... read the essay, if only to put a context around this quote that was contained therein:
"Free enterprise does not mean shredding the social safety net, but championing policies that truly help vulnerable people and build an economy that can sustain these commitments. It doesn’t mean reflexively cheering big business, but leveling the playing field so competition trumps cronyism. It doesn’t entail “anything goes” libertinism, but self-government and self-control. And it certainly doesn’t imply that unfettered greed is laudable or even acceptable."
-Arthur C. Brooks
