At the urging of double bassist John Grillo, I recently took the Meyers-Briggs Personality Test. If you haven’t ever taken this test, check it out here–it is quick, and the results are interesting. You can read more about the test at this Wikipedia page.
I came out as a type eNFj, which is a Teacher Idealist. Here is a summary of this type from Keirsey.com:
The Idealists called Teachers are abstract in their thought and speech, cooperative in their style of achieving goals, and directive and expressive in their interpersonal relations. Learning in the young has to be beckoned forth, teased out from its hiding place, or, as suggested by the word “education,” it has to be “educed.” by an individual with educative capabilities. Such a one is the eNFj, thus rightly called the educative mentor or Teacher for short. The Teacher is especially capable of educing or calling forth those inner potentials each learner possesses. Even as children the Teachers may attract a gathering of other children ready to follow their lead in play or work. And they lead without seeming to do so.
Teachers expect the very best of those around them, and this expectation, usually expressed as enthusiastic encouragement, motivates action in others and the desire to live up to their expectations. Teachers have the charming characteristic of taking for granted that their expectations will be met, their implicit commands obeyed, never doubting that people will want to do what they suggest. And, more often than not, people do, because this type has extraordinary charisma.
The Teachers are found in no more than 2 or 3 percent of the population. They like to have things settled and arranged. They prefer to plan both work and social engagements ahead of time and tend to be absolutely reliable in honoring these commitments. At the same time, Teachers are very much at home in complex situations which require the juggling of much data with little pre-planning. An experienced Teacher group leader can dream up, effortlessly, and almost endlessly, activities for groups to engage in, and stimulating roles for members of the group to play. In some Teachers, inspired by the responsiveness of their students or followers, this can amount to genius which other types find hard to emulate. Such ability to preside without planning reminds us somewhat of an Provider, but the latter acts more as a master of ceremonies than as a leader of groups. Providers are natural hosts and hostesses, making sure that each guest is well looked after at social gatherings, or that the right things are expressed on traditional occasions, such as weddings, funerals, graduations, and the like. In much the same way, Teachers value harmonious human relations about all else, can handle people with charm and concern, and are usually popular wherever they are. But Teachers are not so much social as educational leaders, interested primarily in the personal growth and development of others, and less in attending to their social needs.
Mikhail Gorbachev is an example of a Teacher Idealist.
