Personal identity is who you are and what makes you unique. It's like a fingerprint - it's what makes you different from everyone else. For example, your personal identity might include things like your name, your age, where you live, your hobbies and interests, your family, your beliefs, and even your physical characteristics like the color of your skin and hair, your height and weight, and your voice. All of these things form your personal identity and make you an individual.
