Personal ambition often serves as a driving force for characters in shaping their sense of identity. It can influence their goals, decisions, and actions, ultimately defining who they are and what they strive to become. Characters with strong personal ambition may be driven to achieve success, pursue their dreams, and overcome obstacles, all of which contribute significantly to their sense of self and identity. In contrast, characters lacking personal ambition may struggle with their identity, feeling lost or unfulfilled without a clear sense of purpose or direction.
