In my opinion human beings are natural copiers of other people. So when we see something we like in another person, we try to do it ourselves. And when a particular person keeps doing wonderful things, we try to be just like them, and they become our role models. There's nothing wrong with this unless it's taken too far, to the point where you believe everything they do is perfect, and they never make mistakes. No one is perfect. If you can keep that truth in mind, I believe role models can serve as wonderful tools for the development of our minds
