In my opinoin, a hero is someone who has positive character and who is willing and brave enough to spread this kind of positive energy to others. In order to become a hero, one does not nessarily have to have superior physical power, however, one must have strong mental power, so called greatness, a noun usually associate with heroes. To devlope this kind of greatness, we must train ourselves to to be more generous, carry more responsibilities,think about others before ourselves and provide help to others when needed. These are the qualities a hero must have and are the essencial things to do for us to become heroes.
