“DEFENSE PESSIMISM: According to psychologist Julie Norem, positive thinking doesn't work for some people, who should try defensive pessimism. Here's how it works: in the face of an anxiety-producing task instead of psyching yourself up, psyche yourself down by consciously lowering your expectations. Rehearse everything that could go wrong, and devise strategies to avert every conceivable glitch. This will produce a sense of control and reduce anxiety, helping you to perform effectively. Or, maybe not.”
