For me, it's Harry Potter. His bravery and determination in the face of adversity inspire me to never give up.
I'd say Hermione Granger has had a huge impact on me. Her intelligence and hard work ethic show that you can achieve great things through knowledge and effort. Also, her loyalty to her friends is something I strive to have in my own life.
The fictional character that's influenced me a lot is Katniss Everdeen from 'The Hunger Games'. Her strength and willingness to fight for what's right, even in the toughest circumstances, make me believe I can stand up for what I believe in, no matter how difficult it seems.
