1. Sometimes people hold a core belief that is very strong. When they are
presented with evidence that works against that belief, the new
evidence cannot be accepted. It would create a feeling that is
extremely uncomfortable, called cognitive dissonance. And because it
is so important to protect the core belief, they will rationalize,
ignore and even deny anything that doesn't fit in with the core belief.
2. It is in the women’s nature to be ungrateful towards their husbands and to deny favours. If you were to be nice to her for her whole life but you grieved her once, she will say, “I have never seen any good from you”. So don’t let this attitude of her make you dislike her or to run away from her. If you dislike this feature of hers, you will be pleased with some other good habits within her, so create a balance.
3. If someone shows you their true colors, don't try to repaint them.
4. You can give a person knowledge, but you can't make them think. Some people want to remain fools, only because the truth requires change.
