Isabel Briggs Myers quotes

“The best-adjusted people are the ‘psychologically patriotic,’ who are glad to be what they are.” 

“For many Extraverts, ‘hell at a party’ is ‘not being able to get in.’ Many introverts see it as ‘being there.’” 

“Introverted feeling types have a wealth of warmth and enthusiasm, but they may not show it until they know someone well. They wear their warm side inside, like a fur-lined coat.”
