Introverts are collectors of thoughts, and solitude is where the collection is curated and rearranged to make sense of the present and future.

Whatever kind of introvert you are, some people will find you 'too much' in some ways and 'not enough' in others.

Your nature is not the problem. The problem is that you have become alienated from your nature -- from your power source.

Introverts are generally more sensitive to low-intensity stimuli - they are mentally alerted to inputs that extroverts may miss.

Extroverts want us to have fun, because they assume we want what they want. And sometimes we do. But "fun" itself is a "bright" word, the kind of word that comes with flashing lights and an exclamation point! One of Merriam-Webster's definitions of "fun" is "violent or excited activity or argument." The very word makes me want to sit in a dimly lit room with lots of pillows-by myself.

Introvert conversations are like jazz, where each player gets to solo for a nice stretch before the other player comes in and does his solo. And like jazz, once we get going, we can play all night. Extrovert conversations are more like tennis matches, where thoughts are batted back and forth, and players need to be ready to respond. Introverts get winded pretty quickly.

Extroverts are more attuned to social rewards, so they are more likely to flash a smile for effect. A notable exception are introverts - like me - whom I call "socially accessible" introverts. We have been trained well to smile and nod, which can place a burden on our processing efforts.
