ENFP/ESTJ: Ne/Te or Te/Ne--Borderline Personality Disorder.
The ENFP I described above may have been one of these types. They simultaneously desire to control and dazzle others with their extraordinary leadership and grandiose performances. For the ENFP, this tends to take the form of insisting on consistent, scheduled attention from others for his/her artistic or creative gifts, while for the ESTJ it tends to manifest itself in terms of indignation when others refuse to follow every detail of the user's "visionary" leadership style. This combination, ironically, makes the user extremely dependent upon others for meaning, never really finding a sense of internal balance, no matter how hard he works to create and delegate. While Te leads these types to desire structure and discipline, Ne continually contradicts it by insisting on impulsive displays of creative freedom. Often self-denigrating over the inability to control Ne's impulsive explorations, Te will go to any lengths to keep the user in a position of power and influence, where others must defer to his authority.*
If Fi/Si were doing its job, these types would recognize that what they're looking for cannot be found outside themselves--they must learn to sometimes live for themselves and only themselves, and forget about external results for a moment.
