I think he is an ENFP:
-He likes putting on a show.
-Likes talking about himself.
-Not attuned to the reception of the audience, more attuned to himself (Fi)
-Enjoys giving unfinished statemetns / half-baked points (ENFP)
But he could also be INFP or even a special kind of ISFP. What do you think?
Oh and does anybody know of any other forums where people disucuss famous peoples' types? I like this one, but activity is slow.
