What are some of the common traps we must avoid at all times?

Praising oneself and condemning others are equally dangerous. Attempting to hide one’s meanness and wickedness, and putting on the mask of goodness, justifying one’s faults and exaggerating one’s attainments - these are also poisonous traits. Equally evil is the habit of ignoring the good in others and assiduously seeking only their faults. Never speak words that demean the other. When we are friendly with another and like them very much, whatever he/she does is certain to strike us as good. When the wind changes and the same person is disliked, even the good he/she does appears to us as bad. Both these reactions are misconceived. They are not commendable at all.
