I don't know if I really have a hero. I don't want to model myself after someone else. I try to be my own hero and often fail, but I guess the point is I keep trying. I also think it can be detrimental to your own self worth if you idolize someone else too much.
The only book I have ever read about a real person is Ghost Rider by Neil Peart (the drummer from Rush). It was about his travels on motorcycle across Canada, America, and Mexico after his daughter and wife had died within a year of each other. His daughter died in a car accident very suddenly, and then his wife died from cancer very soon after. It was one of the saddest things I have ever read. When Neil Peart wrote about it, he seemed to believe that his wife had given up because her daughter was killed so suddenly, and that was why she lost the battle with cancer. I don't know if he was right or not, but I am sure her daughter's death didn't help.
I guess you could sort of think of him as being heroic, going on with life after such a horrible tragedy. But everyone has their own struggles in life, and I think it's important that we all be heroes for ourselves, as much as we can be.
