Role Model is a person who serves as an idol for others and inspires confidence in them. There are people whom we wish to emulate. It might be their behavior, charm, personality, success and career graph that becomes an example before people which is worth emulating. You can always have a role model or some person whom you really idolize. Your role model is generally the same kind of person that you aspire to become someday. It is great to have a role model and take inspiration from someone's inspiring life.
Having a role model is a great idea, but one should not go about aping every little thing that our role model does. It is important to retain your individuality. Go about emulating and not aping your role model. You can always learn and pick up new things from others but always believe in setting your own example. Even you can be a role-model to someone.
