What do experiences contribute to in a person's life, according to the material?

Experiences significantly contribute to forming beliefs about oneself, which is crucial for personal development and mental health. These beliefs are shaped through various life events, challenges, and interactions, impacting a person's self-esteem and identity. The way individuals interpret their experiences can lead to positive or negative beliefs about their capabilities, worth, and place in the world. For instance, overcoming obstacles can enhance self-efficacy, while negative experiences may foster limiting beliefs. Understanding this process is foundational in peer support, where individuals share their experiences to promote growth and resilience in others.
