Friendships influence how we perceive challenges, such as judging a hill as less steep when accompanied by a friend. They enhance academic performance, help manage setbacks, and improve health. Childhood and teenage friendships shape beliefs and emotional growth. However, making friends can be difficult due to the 'liking gap,' where people underestimate how much others like them. Psyching oneself up and expecting to be liked can improve social interactions. Building intimate friendships involves companionship and closeness, which can be fostered through shared activities and consistent communication. Even long-distance friendships can thrive with regular, meaningful interactions. Challenges in friendships, especially during teenage years, can arise from competition or lack of support. Addressing conflicts through open, non-judgmental communication can strengthen bonds. While some friendships end, all can benefit from healthy habits, and it's never too late to form new ones.
