The difference is between gaining a skill vs loving what you do. Introverted person practice socializing is more of a skill development than actually loving every moment of it. True introverts are happy being alone (they are not lonely as in a negative sense).

I think it is easier for introvertes to gain extrovertion skill (clear benefits) than extroverts to gain introversion skills (benefits of being alone is not that obvious)
