Here's a conversation on another blog about extroverted vs. introverted youth pastors. If there is a ministry of the church that is more extroverted than youth ministry, I don't know what it is. I can't tell you the number of job descriptions I found for youth pastor positions that involved words like "dynamic," "charismatic," or "excitable." While I haven't worked in youth ministry, I have worked quite a bit in college ministry, and the expectations for extroverted leaders were enormous.
Go over there and add to that conversation!
