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

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.

Introvert conversations are like jazz. Each player gets to solo for a nice stretch before the other player comes in and does his solo.

Though introverts are drained by interaction, we can take immense pleasure in watching the scene around us.

Introverts tend to internalize problems. In other words, we place the source of problems within and blame ourselves. Though introverts may also externalize and see others as the problem, it's more convenient to keep the problem "in house." Internalizers tend to be reliable and responsible, but we can also be very hard on ourselves.

A good rule of thumb is that any environment that consistently leaves you feeling bad about who you are is the wrong environment.

As an introvert, you can be your own best friend or your worst enemy. The good news is we generally like our own company, a quality that extroverts often envy. We find comfort in solitude and know how to soothe ourselves. Even our willingness to look at ourselves critically is often helpful.But, we can go too far. We can hoard responsibility and overlook the role others play. We can kick ourselves when we're down. How many times have you felt lousy about something, only to get mad at yourself for feeling lousy?
