Maybe this is OT, but as an introvert myself I really enjoyed the book "Quiet" by Susan Cain. That book has also been discussed on NPR somewhere. Generally it talked about the differences between introverts and extro(a)verts and how our society is extravert-centric. But what I really enjoyed about it for myself is it was very positive about the value of introversion, which has made it easier for me to enjoy and value my own introversion and not to feel guilty about it. I have also given myself permission more often to say no to things that I know I will not enjoy due to being introverted, and to schedule down time when I know I will need it (e.g., visiting the in-laws, all of whom are very extraverted and most of whom are delightful wink

I don't remember if it specifically talked about introverted and gifted, though; I think it was more there are different kinds of people and they need different kinds of things to be happy. But well-argued, considered, and informative, IMO.
