Self-esteem describes the feelings of worthiness and value that one assigns to themselves as a person. A multitude of factors affect one's self-esteem, including life circumstances and input from mentors and relatives. Self-esteem development begins at a very early age. Researchers suggest that humans have the capacity to develop self-esteem as soon as they can recognize their own name. Problems with self-esteem start to occur when one or more needs fail to get fulfilled. Specifically, the needs for belongingness, attention, affirmation, safety, and love must be fulfilled in order for healthy self-esteem development to occur.
