wont make a statement about type, but list what properties of him caught my eye:
i had him read his book to me, and watched him on youtube and watches his initiation speak. maybe i dont know enough.
he has this slow learner, observer, slow decision maker live style (much like malcom x). builds up his values or insight (N or T) more, than he acts them out (unlike E). is minimalistic about acting out anything. tries to live the impersonal life without properties (very T, totally unlike enfj), other than carefully applied actions. he is involved with people because he is cool about formal interaction (T), but he is involved without assuming control (unlike EJ), he listens, takes advice but does not become attached (not like Fe). building up values or insight by observation, not by trial and error (unlike Te or Ne). he applies them, when they are finished, in a stage process (very I). then he won't change them anymore (somehow J). he is not very situational, he wants to be(come) his own example of truth (Ti) Or channel his vision (Ni). his ability to survive and rise in politics would indicate Ne rather than Ni, especially if he is not Te dominant. but if he were entp, he is hiding this, and emphasises his director image (IxxJ). for good reasons. nobody would trust an entp president.if he is Ti, than he has strong Ne, which is to be expected from a person who is developed, which brings me to another point:
his motivational talk is mostly coming from a stage of development. it's not an indication of enfj. it's not an indication of his type. but there is N in the wordings. not in his message. this man is not a slave of his functions. he does not hear voices like ("make this plannet into an ENFJs dream"). if you reduce his message to something like that, then you did not get it.
i think his N is more apparent in how independent (almost isolated) he is in his live style (values and thinking).
i believe that transparency (that youtube thing) is a value in introverted people, because they don't like to feel excluded, but the superficiality of the world is usually making them feel excluded (blind and insecure), even when they are integrated and behaving in an extroverted way. extroverted people feel that superficial insight is all that is of real value, therefore they don't feel blind. however the youtube transparency is also a stage move.
