A pessimist is a person who tends to see the negative side of situations and expects unfavorable outcomes. They often focus on potential problems rather than possibilities, which can lead to a more cautious or fearful approach to life. This mindset can affect their decision-making and relationships, as they may struggle to see the positives in various scenarios. Pessimism can be contrasted with optimism, where an optimist looks for the good in situations and anticipates positive results. While pessimism can sometimes help individuals prepare for challenges, excessive pessimism may lead to feelings of hopelessness and anxiety, impacting overall well-being.
