It is easier for an artful Man, who is not in Love, to persuade his Mistress he has a Passion for her, and to succeed in his Pursuits, than for one who loves with the greatest Violence. True Love hath ten thousand Griefs, Impatiencies and Resentments, that render a Man unamiable in the Eyes of the Person whose Affection he sollicits.
If you're a man in your twenties or thirties, and you have yet to make your fortune, I would urge you not to get married.
