The Laws of Human Nature
If you come across any special trait of meanness or stupidity . . . you must be careful not to let it annoy or distress you, but to look upon it merely as an addition to your knowledge—a new fact to be considered in studying the character of humanity. Your attitude towards it will be that of the mineralogist who stumbles upon a very characteristic specimen of a mineral.
Throughout the course of our lives, we inevitably have to deal with a variety of individuals who stir up trouble and make our lives difficult and unpleasant. Some of these individuals are leaders or bosses, some are colleagues, and some are friends. They can be aggressive or passive-aggressive, but they are generally masters at playing on our emotions. They often appear charming and refreshingly confident, brimming with ideas and enthusiasm, and we fall under their spell. Only when it is too late do we discover that their confidence is irrational and their ideas ill-conceived. Among colleagues, they can be those who sabotage our work or careers out of secret envy, excited to bring us down. Or they could be colleagues or hires who reveal, to our dismay, that they are completely out for themselves, using us as stepping-stones.
