Overconfidence can also beget daily temptation, to which you intentionally and unnecessarily subject yourself regularly. Overconfident alcoholics keep a bottle of booze in their desk drawer, to “remind” themselves. Ex-smokers stash a pack or two at home to “test willpower.” Dieters buy high-calorie goodies “just in case company drops in.” Intentionally exposing yourself to substances or situations you are trying to avoid is not a sign of strength, a measure of willpower, or a positive reminder. Sooner or later temptation wins and you lose.
