i think that the wording of this question is just too general. whenever i introduce myself, which aspects of my personality that i do highlight changes from person to person. if im meeting with an interviewer for a job position, i highlight different points of my personality than if im meeting my friend's mom, and those aspects are different when i meet my mom's friend, if you catch my drift.
Apart from who it is that im meeting, i generally dislike talking about myself because i highly dislike sounding like a pompous ass. usually, i like to just listen to others, and let my actions speak for me.
