Introversion is defined as the directing of interest inwards towards one's own thoughts and feelings rather than towards the external world or making social contacts.  In our society there is a current devaluing of this characteristic. There is a high value placed on extroversion, which has caused an imbalance.  In this video, author Susan Cain talks about this imbalance.
