"Trying to know yourself" or "defining yourself" or "trying to be authentic"... I just can't imagine an ESTJ doing that!
Just add "by introspection" to the sentences above and you're right into INFP terrain...
I'm not trying to define or understand myself. To me, I am not that interesting - MBTI is. I'm using myself (and husband, and others) to try and understand MBTI.
Can I get my extravert badge now?
