To improve your mood and mental health long-term, evaluate if you like your job. It doesn’t matter so much if you get paid well, as much as if you’re satisfied with what you’re doing. Does your work challenge you? Do you feel creative and productive at work? If you don’t like your job, but for some reason cannot quit and find something different, do other activities and hobbies that bring you joy. As long as you’re doing something personally meaningful and fulfilling to you, you’ll improve your mood. Humans are social by nature, so make sure you’re not isolating from other people. Create a network of supportive people, whether that’s friends, family, and/or coworkers, and interact with them on a daily basis. Surround yourself with people who will listen well without judging, help you reach goals, and be there for you during rough times. If you’re having trouble meeting new friends:  Avoid spending so much time using your phone, computer, or TV. Get outside and interact face-to-face with people! Join a support group, a professional networking group, or a club. Take a class at the gym. Take a walk and introduce yourself to neighbors. Volunteer.
