Introvert checking in. I support a sales organization, so I'm surrounded by extroverts. What I've learned is they are horrible listeners. I use this as a strength for me. I pick up on details they don't and I believe that empowers me.
Everything else said here applies to me. My batteries get drained and I need downtime from people to recharge. The good news is there has been a lot of research and books on this subject in recent years ("introvert advantage", "silence: the power of quiet..."). I personally need to see this as a positive even if the western world places more emphasis on extroverts.
