Oh, man, I totally used to pose myself after my favorite TV/movie characters as a teenager! I used to sort of “be” the characters in my mind, like trying on a new personality. There would have to be characters for several stages of my life, so here goes:
6–7 years old: Punky Brewster
8–9: Stacy from Kids, Incorporated
14–15: Angela from My So-Called Life
16: Mia Wallace from Pulp Fiction
In my early 20s, I was more into writers, so i would have to say
20–21: Sylvia Plath
As my 20s progressed, I felt less akin to characters, as I was getting a better sense of my self, so I stopped looking outward for that sort of thing.
The TV characters I love to hate nowadays are: Brenda from Six Feet Under, Sookie from True Blood, and all the characters from Big Love.
