Pessimism is a mindset characterized by a tendency to expect negative outcomes or focus on the worst aspects of a situation. Pessimists often believe that challenges are insurmountable and that their efforts will not lead to success. This outlook can affect decision-making and overall well-being, as it may lead to feelings of hopelessness or anxiety. In psychology, pessimism is often contrasted with optimism, which is the belief that positive outcomes are possible. While some level of pessimism can be protective, helping individuals prepare for potential difficulties, excessive pessimism can hinder personal growth and relationships. Understanding this balance is important for mental health.
