I would think about times when you have “saved” someone or helped someone out tremendously that you would be considered heroic. Have you ever stopped someone from getting hurt? Hosted a fund raiser for an important cause? They do not have to be big things either. Some people consider you a hero for just being there for them. My suggestion would be to start with your own personal experience with being a hero in your everyday life. Because I would write an essay/paragraph FOR you but that is MY personal experience not YOURS. Let me know if you need any future help during your writing process and I’m wishing you the best of luck!! :)
