There’s a term in sports called, colorfully, “the yips.” It’s when a player starts to mess up something they do all the time–shooting free throws, making a short putt, throwing over to first base. It’s not just being bad at the sport, or slowing down from age or injury–it usually involves something easy that the athlete has done hundreds and hundreds of times, something that is now just muscle memory and instinct. The yips come into play when something comes between that instinct and action. That thing is their mind.
An athlete with the yips suddenly starts thinking about messing up, instead of not thinking at all and letting their training take over. They question every motion, and that starts to become self-perpetuating. Some of them “yip” themselves right out of the game. These highly-trained people, who have been among the best in the world at what they do, can give it all away through self-defeating behavior. People who already have significant problems can be affected even worse. Self-defeating tendencies, the tendrils of self-doubt, can impact anyone. For people suffering from a mental disorder and working toward recovery, self-defeating behavior can be a great enemy, a threat multiplier, and something that needs to be overcome.
