This is one of my favorite quotes from the great Don Draper of Mad Men. The full quote goes like this:
"The reason you haven’t felt it is because it doesn’t exist. What you call love was invented by guys like me, to sell nylons. You’re born alone and you die alone and this world just drops a bunch of rules on top of you to make you forget those facts. But I never forget. I’m living like there’s no tomorrow, because there isn’t one."
