There's an interesting article (and quiz) in the Wall Steet Journal on HSP's (Highly Sensitive People). http://www.wsj.com/articles/do-you-cry-easily-you-may-be-a-highly-sensitive-person-1431971154
Thanks to Paul Ekman for the link.
The part I found interesting was:
HSPs are currently having a moment: Last week, the First International Scientific Conference on High Sensitivity or Sensory Processing Sensitivity was held at the Vrije Universiteit Brussel, with panels on sensory processing sensitivity in children and what we can learn from successful people who are highly sensitive. There is a documentary in the works titled “Sensitive.” (The trailer features Alanis Morissette, a self-proclaimed HSP.)

As both an introvert and HSP I think of being an HSP as my superpower. Or satying it more clearly when you learn to live intentionally (mindfully) being an HSP becomes a superpower.
