In life, people have dreams and goals that they desire to fulfill or achieve. For instance, some have the desire to become a musician, an actress, and so on. A lot of times, achieving these sort of dreams require having a role model(s) which you look up to. These role models are people who have made resounding success in your area of interest.
To have a role model means you can imitate to an extent some of the qualities your role model has. It does not mean you have to copy everything they do. It does not mean you cannot bring in your own flavor, creativity, originality, and style into what you do.
It is good to have role models. It is also good to realize that in as much as you can imitate your role model, you have something unique which your role model does not have. When you try so hard to be like your role model you end up being someone else, not you.
