词义猜测 People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well-prepared dishes, the goodness of the wine, and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things.Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society ,offend (hurt) many people, and make themselves disagreeable everywhere. The tendency of criticizing and being disliked is perhaps taken up by imitation. It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.
