〉What is one piece of advice you would give an incoming freshman?
A piece of advice I would give is that high school goes best when you allow yourself to grow beyond who you think you’re supposed to be. Don’t rush the process or compare your path to others.
〉What will you miss most about high school?
Seeing the same people everyday and growing up alongside my peers, sharing stories and knowledge.
〉What are you most excited about after graduation?
I am most excited about stepping into new environments and perspectives. Whether through education or meeting people from different cultures and backgrounds, I look forward to continuing to learn.
〉Who inspires you the most and why?
My mother inspires me the most. She moved across the world without speaking English and sacrificed everything she knew to give our family a better future. In the middle of her life, she changed careers, faced uncertainty head-on, and carried immense responsibility with resilience and grace. Her courage, adaptability, and unwavering commitment to our family have taught me the true meaning of strength and perseverance.
〉What’s your favorite high school memory?
Going to the Homecoming football games enjoying the atmosphere of Colt Country.
