There are two types of people in the world. Although they have equal degrees of health and wealth and the other comforts of life, one becomes happy, the other becomes miserable. This arises from the different ways in which they consider things, persons, the events, and the resulting effects upon their minds.
The people who are to be happy fix their attention on the conveniences of things, the pleasant parts of conversation, the well-prepared dishes, the goodness of the wines, and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the contrary things. Therefore, they are continually discontented. By their remarks, they sour the pleasures of society, offend many people, and make themselves disagreeable everywhere. If this turn of mind were founded in nature, such unhappy persons would be the more to be pitied. The tendency to criticize and be disgusted is perhaps taken up originally by imitation. It grows into a habit, unknown to its possessor. The habit may be strong, but it may be cured when those who have it are convinced of its bad effects on their interests and tastes. I hope this little warming may be of service to them, and help them change this habit.
Although in fact it is chiefly an act of the imagination, it has serious consequences in life, since it brings, on deep sorrow and bad luck. Those people offend many others, nobody loves them, and no one treats them with more than the most common politeness and respect, and scarcely that. This frequently puts them in bad temper and draws them into arguments. If they aim at obtaining some advantage in rank or fortune, nobody wishes them success. Nor will anyone speak a word to favor their hopes. If they bring on themselves public disapproval, not one will defend or excuse them. These people should change this bad habit. If they do not, it will be good for others to avoid any contact with them. This passage tells us that those who are always dissatisfied with the situation they are in will live______.
