I am studying art and my topic is identity. Anyone have ideas about what relates to identity and how to express it. I need to create a final piece with meaning behind it.

Maybe you could talk about how hard it is to find an identity, but how once you have it it never leaves

or:

different people have different identities, but that doesn't change who they are.

Bad identity joke- My friend david was a victim of id theft, now we just call him dave
