The document discusses the relationship between optimism and success. It summarizes research by Martin Seligman showing that optimists tend to be more successful than pessimists. The research studied employees at MetLife and found that those who scored as super optimists on a test outperformed pessimists by 21% in the first year and 57% in the second year. Optimism is characterized by seeing negative events as temporary rather than permanent, specific rather than universal, and believing one has control rather than helplessness. The document encourages practicing an optimistic explanatory style to help achieve success.
