Optimism is an outlook on life such that one maintains a view of the world as a positive place. It is the opposite of
pessimism. Optimists generally believe that people and events are inherently good, so that most situations work out in the end for the best.A common conundrum illustrates optimism-versus-pessimism with the question, does one regard a given glass of water, filled to half its capacity, as
half full or as half empty? Conventional wisdom expects optimists to reply, "Half full," and pessimists to respond, "Half empty" (assuming that "full" is considered good, and empty, "bad").
