Optimism is an attitude characterized by hope, confidence, and the belief that the future will be good; it is largely tied to self-esteem and resilience. Optimists tend to draw on internal resources to overcome challenges, viewing obstacles as opportunities for learning. However, while the benefits of a positive outlook on life are numerous—lower stress, persistence, greater achievement, increased longevity—an overly rosy outlook can be used as a method of avoidance or as an invalidation of others’ feelings. Fostering a healthy sense of optimism can come naturally to some and can be a journey for others; most consider practicing mindfulness and gratitude as some of the soundest methods to start your optimism practice.
