A bad mood is often the reason for blaming others; but very often blaming others causes bad feelings in us; the more we blame others, the worse we feel.

One of our most common and widespread prejudices is that every person has a fixed, special characteristic, that there are kind people and evil, clever people and stupid people, and cold or hot people. But people are not like this; we can say about a person only that he is more often cold than hot. We always divide people like this, but it is no less wrong.

If there is animosity between two people, both are to blame. Any number you multiply by zero, however big, will equal zero. If there is animosity, then, it is the animosity of two people toward each other, and it exists in both of them.

Try to understand and remember that a person always tries to do what is best for himself. And if he is right when he does the best thing for himself, it is good; but if he is mistaken, it is bad, because suffering will follow after such a mistake.

If you remember this, then you will never be upset by anybody, you will never reproach anybody, and you will never be an enemy to anybody. 

— After Epictetus

If you are living with another person, make an agreement that as soon as either of you starts to blame the other, you will end the argument.
