"A hero should be someone who is mainly willing to be brave and put him or herself aside for others. A hero would more than likely have have good intentions towards the things they do, benefiting others in the process. He or she should not perform heroic deeds in search of revenge, fame, and popularity, or a reward in exchange. A hero doesn't need the biggest muscles, the fastest legs, the smartest brain, or even super powers. As long as he or she has a big heart and a great amount of justice, they can be a hero."
So there are some typos and grammar errors...but damnit if this kid didn't hit it on the head.
