Introverts are constantly encourage to become extroverts.  But what exactly is an extrovert?  An extrovert is someone who is constantly performing roles for other people.  And he knows how to play those roles well, and now enjoys playing them.  The introvert, on the other hand, generally performs no roles.  He simply does whatever he does for himself.  to the extent that the introvert has freed himself, through involuntarily, from performing for an audience, his action is more authentic than the extrovert's.  But as his action does not have an external object, it is not authentic or real action.  There is no need, though, for the introvert to become like the extrovert.  All he needs do in order to achieve authenticity is to add an external dimension to his action.  He should do for others as he used to do fro himself.  Exteriorizing the authenticity of introverted action is the path to authenticity.  The person thus makes a quantum jump beyond taking.  He realizes that giving is what makes taking authentic.  He takes only in order to give.

Introvertness is a reflection of extrovertness that gains a level of authenticity over extrovertness, because it is authentic action with an authentic object.  But action can achieve full authenticity only in a Kantian universalization.  It is not, then, merely conformism in order to survive.  Rather, it is an expression of what action really is.  It may not receive the same plaudits as extrovert action.  But there are other kinds of plaudits.
