6 ways to be happier at work

1. Practice looking for the good. People who keep a daily "gratitude list" become happier and more successful over time.

2. Have some fun. Research shows that bursts of lightheartedness, whether from a smile shared with a colleague or a funny clip on YouTube, actually cause people to think more clearly and creatively.

3. Brighten your office space. Everything around you affects your frame of mind. Surround your desk with pictures and objects that lead you toward positive thoughts.

4. Keep a journal. If you find yourself worrying about bad news, a scary rumor, or a stressful deadline, take three minutes to write down how you're feeling. The simple act of putting emotions into words immediately decreases their magnitude.

5. Invest in people. Smart people do stupid things during times of stress, like shutting down their social networks to focus on work. The greatest predictor of success during stress and challenge is the quality and quantity of your relationships.
