Be an Optimist
Be an optimist because without hope you will be miserable. Start with positive self-talk. This not only will help emotions, the body, but the mind. It could help with depression, reduce tension, and reduce the risk of cardiovascular diseases. This has baffled some researchers.
Mayo Clinic suggested a theory.
“One theory is that having a positive outlook enables you to cope better with stressful situations, which reduces the harmful health effects of stress on your body. It's also thought that positive and optimistic people tend to live healthier lifestyles — they get more physical activity, follow a healthier diet, and don't smoke or drink alcohol in excess.”
