I find the "gets energy from" definition to be too situation-dependent. All personality trait definitions suffer from this, but some more than others. Consider an extrovert who just spent a whole week not getting any privacy, not even to use the loo. That person may very well test as an introvert at the end of the week. Or consider an introvert who has been isolated from her closest friends for a month due to an illness. That person may test as an extrovert at the end of the month. I tend to think of introversion as "tendency to be content with solitude", the difference being that instead of needing to recharge by being alone, an introvert is OK with being alone for a time. Most introverts still need social interaction, but they want to set the terms of that interaction. I also think of introversion as "tendency to rely on inner dialogue". I have to go away and be alone to understand a problem, then come back and discuss the solution. Other people need someone else to provide that dialogue; I imagine them as having an inner monologue, but I can't see inside their minds. I'm not a psychologist and I don't know if these definitions hold water. I'm just an introvert who over a lifetime has learned it can fun to be outgoing, and that being a leader requires practice and a good role model, regardless of whether you are introverted or extraverted.
