Basic personality traits develop early in life and over time become inviolable, hardwired. Most people learn little from experience, rarely thinking of adjusting their behavior, see problems as emanating from those around them, and keep on doing what they do in spite of everything, for better or worse.

Other people are not here to fulfill our needs or meet our expectations, nor will they always treat us well. Failure to accept this will generate feelings of anger and resentment. Peace of mind comes with taking people as they are and emphasizing the positive.

Life has a way of taking its toll on the person you thought you were.

There are lots of reasons why a woman stays with a man, even when she's given up on changing him and can predict with certainty the shape that the rest of her life with him is going to take.

In asserting that people don't change, what she means is that they don't change for the better. Whereas changing for the worse, that goes without saying.
