All her life, she had been praised for her principles and her strong sense of right and wrong. More often than not, she was held forward as an example to emulate, a role model to follow. It happened more often than she was comfortable with, but being herself, she never let it show.
The praise is not false, mind. It is quite on the money, in fact. But it rings true for the wrong reasons.
Thing is, she is not guided by principles or strong commitments. She is driven by a brutal and relentless neuroticism, and is literally unable to act any other way. Given time, this tendency will burn her out, but until then, she will be the one to shine the brightest.
