Positive thinking is a mental and emotional attitude that focuses on the bright side of life and expects positive results. A person who thinks positively believes that good things will happen and that negative events will eventually work out. Positive thinking is not just a state of mind; it is also a lifestyle. People who think positively tend to take better care of themselves, are more likely to stay healthy, and live longer than those who think negatively. Positive thinking has been shown to improve immunity, lower stress levels, and increase lifespan. So if you’re not a positive thinker, now is the time to start!
