Most everyone has a role model in their life. They could be a parent, a friend, a teacher, or a sports hero. They could be an officer who works in your school.
A role model is hard to define, because it can be different for everyone. Who your role model is depends as much on you as it does on the person you admire. Often, it is someone you would like to be like when you get older, or someone who does something you find hard to do.
They might be somebody who performs outstanding volunteer work. They might be a community leader. They might be your mentor. Maybe they are generous and kind. Maybe they performed an extraordinary feat or accomplishment. They might be someone in your neighborhood, or someone in another country.
Typically, a role model is brave, smart, strong, kind, thoughtful and fun. Not that every role model is perfect. Unless it is someone out of a storybook, role models are people who might be outstanding in only one or two areas. Or maybe it is someone who is far less than perfect, but is working to improve himself or herself.
