Probably one of the most accurate things I've read about myself. Except for the adrenaline junkie . I like adrenaline but that's probably because I'm not a full introvert. I'm an introvert with a bit more juice for social interaction.
Introverts are capable of acting like extroverts for the sake of work they consider important, people they love, or anything they value highly. We can extrovert the hell out of something interesting and worthwhile, for a period.
