"A practical takeaway from this study is that we’re all liable to take for granted the familiar people and things in our lives when we’re feeling good. But our usual assumption that this has something to do with those people or things is off base. It’s not them but us that changes how warmly they glow. And when times get tough, it should come as no surprise that their warmth suddenly feels indispensable, like the only fire keeping us from dying in the cold." - Fred Yankowski
