Here is a marvelous website: My Hero, which was set up by "The MY HERO Project," a non-profit organization, to "celebrate the best of humanity," as is its statement.
I came across this website when I was searching for more information about Dr. Ben Carson and his books. Just click on "Stories," which is on the top menu bar, and you can go to "Directory of Heroes." There you will be amazed at the different categories of heroes. Even animals are counted in. It’s interesting to think of a name of your hero and try to guess which category he/she falls into. It could be more interesting if you try to put yourself into a category. You can also be a hero in someone’s mind! Well, you can contribute a hero story to the project.
