Christine Carter, Raising Happiness, page 55 …The Perils of Perfectionism
There is a fine line between persistent practice and perfectionism. Perfectionism is the dark side of consistent hard work; it produces a chronic feeling that nothing is good enough and the worst thing in the world is failure. Instead of enjoying the process and deriving satisfaction from a job well done–not to mention growing and learning from mistakes–elevated stress hormones coursing through perfectionists’ blood make them more prone to a host of health problems, including depression, severe anxiety, and a higher incidence of suicide.
Help your kids ward off perfectionism by teaching them how to "satisfice" instead of maximize, as discussed in Raising Happiness.
