One of the symptoms of an approaching nervous breakdown is the belief that one’s work is terribly important.

Truly, if you want to ascertain what love there is in you or in another person, then pay attention to how he relates himself to one who is dead. If one wishes to observe a person, it is very important for the sake of the observation that one, in seeing him in a relationship, look at him alone. When one actual person relates himself to another actual person, the result is two, the relationship is constituted, and the observation of the one person alone is made difficult. In other words, the second person covers over something of the first person; moreover, the second person can have so much influence that the first one appears different from what he is. Therefore a double accounting is necessary here; the observation must keep a special account of the influence the second person has on the person who is the object under observation through his personality, his characteristics, his virtues, and his defects. If you could manage to see someone shadowboxing in dead earnest, or if you could prevail upon a dancer to dance solo the dance he customarily dances with another, you would be able to observe his motions best, better than if he were boxing with another actual person or is he were dancing with another actual person. And if, in conversation with someone, you understand the art of making yourself no one, you get to know best what resides in this person.

I united the majority of well-informed persons into a club, which we called by the name of the Junto, and the object of which was to improve our understandings. ... The first members of our club were...
Thomas Godfrey, a self-taught mathematician, and afterwards inventor of what is now called Hadley's dial; but he had little knowledge out of his own line, and was insupportable in company, always requiring, like the majority of mathematicians that have fallen in my way, an unusual precision in everything that is said, continually contradicting, or making trifling distinctions—a sure way of defeating all the ends of conversation. He very soon left us.
