I'm not into superheroes much, but In real life: I had good people around me that I looked up to. My parents, members of my family I would go into it more, but I will leave it at that. Throughout my life I was inspired by good people around me, nobody sticks out as out of the ordinary, as imperfect as everyone is, I've always found good things in everyone. People from history also have inspired me.
As for a fictional Superhero: One of my favorite superheroes has always been Spiderman. I think because I felt much like a nerd, awkward, and an outsider. I liked that their life was simple and the original not a super genius, not rich, not well connected. I liked that Peter Parker was just an ordinary person, with a crush on his neighbor. I liked the humor and kindness always in the face of adversity and challenge. He has humble and quiet and unassuming people, surroundings, and personality. I'm not sure I like what they did to him as a character nowadays, but I really liked them because I found so much relatable.
