A word to the wise - 

"Just as faces differ in appearance, so people differ in character, and one person's strengths cannot be expected in another. A man who is calm, self-disciplined, and faithfully does his duty may not be deeply moved by sympathy or warm friendship. Don't expect him to greet you with great enthusiasm or display an affectionate, expressive heart. 

On the other hand, someone known for passionate zeal, unwavering integrity, and boldness in confronting evil may also be blunt, lacking social polish and tact, sometimes wounding others by speaking hard truths without gentleness.

One fault of modern society is that people of different classes and professions have become so alike that distinctive characters are less common. We have fewer eccentrics, but also fewer truly original people. Everyone is expected to know a little about everything and to conform to fashionable manners, leaving little room for deep expertise or strong individuality. The result is a society that is polished, but often dull and uniform.

Let us study human nature. The person who understands it knows what to expect from each individual—wise advice from one, heartfelt sympathy from another, and pleasant company from someone else. Such a person understands the motives and weaknesses of others and can make allowance for them as naturally as an engineer accounts for friction or a navigator for a compass's slight imperfections."
