role model
A person whose behavior you admire and want to copy.
A role model is someone whose behavior, accomplishments, or character others look up to and try to imitate. When you have a role model, you watch how that person handles challenges, treats others, or pursues their goals, and you think, “I want to be more like that.”
Role models can be famous figures like scientists, athletes, or historical leaders, but they're often people you actually know: a teacher who makes learning exciting, an older sibling who works hard at school, or a neighbor who helps everyone on the block. What makes someone a good role model combines their achievements with how they got there and how they treat people along the way.
You might have different role models for different parts of your life. Maybe you admire one person's creativity, another's determination, and someone else's kindness. The key is that role models inspire you to develop your own strengths and become a better version of yourself.
Being a role model is also a responsibility. When younger kids look up to you (whether you realize it or not), your actions matter more than you might think. How you handle losing a game, how you treat someone new at school, or how you respond when something goes wrong: all of these moments might be teaching someone else what's possible.
