Rory Sutherland, vice chairman of Ogilvy Group: Perspective is Everything

“Reality isn’t a particularly good guide to human happiness.”

“The circumstances of our lives actually matter less to our happiness than the sense of control we feel over our lives.”

“When you can’t smoke, if you stand and stare out of the window on your own, you’re an antisocial, friendless idiot. If you stand and stare out of the window on your own with a cigarette, you’re a fucking philosopher.”
