The Oxford English Dictionary defines
optimism as having "hopefulness and confidence about the future or successful outcome of something; a tendency to take a favorable or hopeful view." The word is originally derived from the Latin optimum, meaning "best." Being optimistic, in the typical sense of the word, ultimately means one expects the best possible outcome from any given situation.
