If you are referring to the book written by Beatrice Sparks, then here are one or two.
"Can't I even have the privacy of my own soul?" p.8.
"I want so much to be someone important, or even just asked out by a boy every once in a while. Maybe the new me will be different." p10.
"Even now I'm not really sure which parts of myself are real and which parts are things I've gotten from books." p11.
"I'm partly somebody else trying to fit in and say the right things and do the right thing and be in the right place and wear what everybody else is wearing. Sometimes I think we're all trying to be shadows of each other..." p16.
I don't want to get to the end of my life and find that I lived just the length of it. I want to have lived the width of it as well. - Diane Ackerman, quoted in "Newsweek"
