This is an excellent TED video presentation by Susan Cain. Susan is a former corporate lawyer and contract negotiator and is a self described introvert. She makes a strong case that in a world where extrovert’s outgoing nature and ability to be social are highly celebrated, introverts also bring extraordinary talents and abilities to the world, and should also be encouraged and celebrated.
