Recent studies point to a resurgence in using positive psychology, which focuses on ways to look at your situation with a positive outlook. The studies find that a positive outlook and attitude can be cultivated in your life, even if you are in a negative place. E. P. Seligman, Ph.D., writes in his book, Authentic Happiness, that optimistic people tend to interpret their troubles as transient and controllable, whereas pessimistic people believe that their troubles last forever and are uncontrollable. He explains that optimism is a strength that helps promote well-being. Seligman calls this optimism a mature defense to help in the process of living.
