Extroverts are always trying to tell introverts that they are shy and that it is a problem to be conquered, when in fact, introverts are authentic as they are and do not need to cure anything.  So good you understand this concept at such a young age.  Took me years to figure out that this was an important nuance of life, and to realize who in my life was an introvert and who was an extrovert and how there is a lack of acceptance by each type of the difference.
