Your brain is a miracle unrivaled by even the most sophisticated technology, but it is a miracle equipped for a different time and place. After millennia of fighting famine, war and pestilence, we now live in a society of greater and greater ease that is increasingly left to fight psychological battles. Obesity will kill more people this year than hunger. Suicide claims more lives annually than war, terrorism and violent crime combined. Your brain is still fighting a war won eons ago and you must steel it for a new battle that rewards patience and consistency over speed and strength.
