There are a lot of heated debates about what defines an introvert or an extrovert. The main accepted definition is that introverts get their energy from being alone, whereas extroverts get their energy from being around other people. But psychologists often discuss two other related parameters: shy versus outgoing. I always assumed that all introverts were shy, but apparently some introverts can be ultraconfident in groups or capable of smoothly delivering presentations. What makes them introverts is that they just can’t take stimulation and large crowds for extended periods of time.
