I also heard a presenter who spoke about the need for gifted kids to practice performance of some sort (music, theater, etc.) Often, they are so "in their own heads" that they have a hard time relating to an audience. This is problematic when they enter the work world and have to talk with supervisors and subordinates.
Acting in a number of plays really didn't help with me being able to talk with supervisors or subordinates.
Possibly because they are taking time away from when I could happily be in my own head.
I suppose I may be giving off the vibe of "please go away, you're interrupting me thinking about things that have nothing to do with my job."
