What can I say that "Sets me Apart" from other applicants? (UC)

One of the University of California Personal Insight Questions: #8: What makes you stand out against other UC applicants that you have not shared with us?

I was thinking of sharing my story of living in poverty with my parents and how their sacrifices to keep a living motivates me to be academically driven (with many academic awards) and how determined/ambitious I am to lifting my family’s status to middle-class in the future.
In addition:
-First to go to college
-Only child
-Live in a very poor environment

(Note: If you’re thinking this topic should be relevant in prompt #5 (challenge), no. I have already discussed another serious challenge in my life in prompt 5).

I understand that this topic may be common for most applicants nowadays, but I don’t have any other unique qualities in my life (I’m basically average)

If this topic shouldn’t be included please let me know! Or if you have any other ideas on how you would respond comment below! (I’m not here to copy them, but I want an idea)

Thanks!!
