Self-identity refers to the understanding and perception of oneself as a distinct individual. It encompasses various aspects, including personal beliefs, values, experiences, and social roles. Factors such as culture, family, and relationships play a significant role in shaping one's self-identity. This concept is often explored in psychology and sociology, where researchers examine how individuals define themselves in relation to others and their environment. Self-identity can evolve over time, influenced by life experiences, changes in social context, and personal growth, making it a dynamic and multifaceted aspect of human existence.
