When people are depressed their energy, activity, and mood levels decrease in a spiral. The lower energy you feel, the less you do, the worse you feel emotionally, and the cycle continues. Being productive can help interrupt that negative spiral and turn it around. The author offers five strategies for how to break the cycle and move forward: 1) As a general rule, try to have one source of accomplishment and one source of pleasure in each of your mornings, afternoons, and evenings. 2) Find the sweet spot between not working enough and expecting too much of yourself. 3) Alternate between easy, medium, and hard tasks. 4) Cultivate a deep-work habit to reduce your need for self-control. 5) Consider getting treatment for your mental health.
