Does art imitate life or does.... oh, who cares

This is probably a bit random, but I wonder if everyone has one actor or actress that he/she "relates" to in most of the characters that the person plays.  The only reason I pose the question is that I feel that just about every character that Topher Grace plays has a strong correlation with my own life.  Maybe it is just that I notice the similarities more in his movies and that they exist in others.  Anyway, I won't go into all the details about why I think Topher is my on-screen double, but I wanted to share the thought.
