I personally believe its actually simpler than that, I may be wrong but I take it as being looked at as a celebrity "through glass" being a camera lense only seeing what youre told you see, and being told that youre supposed to be interesting and act a certain way because that's who you are to people. When really he wants to be seen as himself and not as the person that the camera says he is. Hince the phrase "how do you feel, that is the question, but I forget you dont expect an easy answer" I think Corey believes that Hollywood wants you to be who the camera glass and the people behind it tell you to be, not yourself.
