The answer is "he strive to become an extroverted personality since his shyness interferes so much with his life."
The vast majority trust that an extrovert is a man who is amicable and active. While that might be valid, that isn't the full importance of extroversion. An extrovert person is a man who is invigorated by being around other individuals. This is the inverse of a self observer who is invigorated by being distant from everyone else.
