Plenty is doing.
"The general remedy of those who are uneasy without knowing the cause, is change of place; they are willing to imagine that their pain is the consequence of some local inconvenience, and endeavour to fly from it, as children fly from their shadows; always hoping for some more satisfactory delight from every new scene, and always returning home with disappointments and complaints... The foundation of content must spring up in the mind: and he who has so little knowledge of human nature, as to seek happiness by changing anything but his own dispositions, will waste his life in fruitless efforts and multiply the griefs which he proposes to remove."
