Fight the blues with behaviors that lift you up. It's a strategy proven to help a person overcome feelings of sadness when those feelings aren't caused by clinical depression, which could require additional assistance. The earlier you act to behaviorally change your mood, the more successful you'll be. Anniversaries, bad weather, disappointments, media news, boredom, or even a movie can trigger sadness. Take charge of your thoughts and decide "not to go there". Then take action. To influence a positive mood, do something you like: dress differently, seek humor, alter the day's schedule, get sunshine, take a brisk walk, or go fishing. What works for you?
