"Perhaps the most striking characteristic of worry, is its absolute impotence. Worry never changes a single thing except the worrier. History has no record of worrying warding off disaster. No tornado has been prevented, no drought averted, no plane kept from crashing, no child kept from falling off his bike, no teenager stopped from skipping classes or trying drugs. No heart attacks have ever been avoided through worry (though a great number have been caused by it). Worry is definitely counterproductive. Like the illustration of a rocking chair, it doesn't get us anywhere, but at least it gives us something to do, and women like to do something."
Linda Dillow, Calm My Anxious Heart
