“Leave an extrovert alone for two minutes and he will reach for his cell phone. In contrast, after an hour or two of being socially “on,” we introverts need to turn off and recharge. My own formula is roughly two hours alone for every hour of socializing. This isn’t antisocial. It isn’t a sign of depression. It does not call for medication. For introverts, to be alone with our thoughts is as restorative as sleeping, as nourishing as eating. Our motto: “I’m okay, you’re okay—in small doses.”

“Do you know someone who needs hours alone every day? Who loves quiet conversations about feelings or ideas, and can give a dynamite presentation to a big audience, but seems awkward in groups and maladroit at small talk? Who has to be dragged to parties and then needs the rest of the day to recuperate? Who growls or scowls or grunts or winces when accosted with pleasantries by people who are just trying to be nice?If so, do you tell this person he is "too serious," or ask if he is okay? Regard him as aloof, arrogant, rude? Redouble your efforts to draw him out?If you answered yes to these questions, chances are that you have an introvert on your hands—and that you aren't caring for him properly.”

“I will say that the socially oblivious extroverts do not represent the whole. As with introverts, social skills are independent of extroversion: some are skilled, some are not. The skilled ones know how to listen. But in contrast to socially unskilled introverts, who keep to themselves, socially unskilled extroverts insist on socializing.”

“That was the day I realized that he could not cope and I could not cope and, emotionally, he could take me down with him. And I discovered in myself an awful determination not to let that happen. From that moment, I was determined to get him out of his apartment and under professional eyes, or, failing that, to protect myself. How to protect myself, I didn’t know. Hire help over his objections? Take him to court and seek to have him declared incompetent? Report him to Adult Protective Services? Use my ownership of his apartment to force him out? All I knew was that, at that point, I believed myself capable of doing such things, or even of washing my hands of the situation if he would not listen to reason. I imagined telling an indignant world that I had tried my best and could do no more. You have no idea what a thing it is to have that sort of conversation with yourself about a parent.”

“What does an introvert do when he's left alone? He stays alone.”

“I’m the kind of person who likes to be by himself. To put a finer point on it, I’m the type of person who doesn’t find it painful to be alone. I find spending an hour or two every day running alone, not speaking to anyone, as well as four or five hours alone at my desk, to be neither difficult nor boring. I’ve had this tendency ever since I was young, when, given a choice, I much preferred reading books on my own or concentrating on listening to music over being with someone else. I could always think of things to do by myself.”

“The Socially Accessible introvert looks like an extrovert on the outside and sees extroversion as a bar that he or she can never quite reach. These individuals are often very successful in social arenas, but fault themselves for not having more fun.”
