I really enjoyed the book The Genius in All of Us. It is extremely empowering, and fully supports my belief in the idea of the huge potential we all have, regardless of ethnicity, where we come from or genetics. The message of the book it that we don't really know what our true limits are.
Doing a Google search on the book unearthed this presentation by the author, David Shenk. Check it out, it's well worth a watch.
