Gaining a deeper self-awareness and self-acceptance of one's racial identity (children who are mixed race, for example)
Finding acceptance through a gender identity
Separating themselves from their parent's identity
Separating themselves from the identity of their friends or peer groups
Being comfortable with oneself despite being different than others around oneself (cultural differences with one's peers after immigrating, etc.)

There are five basic human needs that, when missing from a character's life, could motivate them to pursue this goal. The following needs are all possibilities, but only one of them should be the primary driver for any given character. For more information on the relationship between human needs and outer motivations, please see this Character Motivation tutorial.

Self-Actualization: Feeling unsure about who one is as opposed to ideas that parents, friends, or society imposes may create a deep enough yearning to explore personal identity to better understand who one really is.
Esteem and Recognition: If the character is being harassed for aspects of who they are and what they do, or are experiencing bias or racism, this could lead to them delving deeper into who they are to learn self-love and acceptance, raising self-esteem.
