A ruminator can either be an optimist or a pessimist. Ruminators who are pessimists are in trouble. Their belief structure is pessimistic, and they repeatedly tell themselves how bad things are. Other pessimists are action-oriented and do not ruminate: They have pessimistic explanatory style, but they do not talk to themselves much at all. When they do, it is usually about what they plan to do, not about how bad things are.
