Optimism: Measures the ability to maintain a positive perspective and stay persistent toward achieving goals, even in difficult circumstances. A straightforward way to increase optimism is to avoid negative and pessimistic people. Misery loves company. Research shows that emotions are contagious. Avoid people who are negative and spend time with positive people. This may sound trite, but it works. If you are around a person at work who constantly gossips or complains, this is directly affecting your mood. Remember that our brains are wired to focus on negativity rather than positivity. The way to change this is to alter your environment by avoiding negative people and by paying attention to your thoughts and behaviors. Rely on your friends to help you feel upbeat, and do things that make you happy.
