A little bit more esoteric is the Enneagram as personality model. Unlike MBTI, the Enneagram describes nine different motives that determines why you do what you do. Most of the INTJs are type 5 (Investigator) which is also without doubt my main driving force. Analytical, distanced, abstract , positive inventive, wise, energetic and negative unfortunately also isolated, nihilistic and eccentric. This usually includes the so-called wings, ie the neighboring types 4 (Individualist, creative, natural, disciplined) or 6 (Loyalist, faithful, courageous, trustworthy).
So far so good. What I could find out was for me that the funny tests on the net did not give a real result, but with some self-reflection, I realized two things: On one hand, I'm a type 5, but the two wings are balanced so I have both a creative and disciplined facet as well as courage and caution affect my actions. What is also very noticeable is the additional type 1 - the Reformer. Perfectionistic, hesitant, scrupulous, positive, critical, calm, ethically supremely and unfortunately also lawful, pharisaic, decomposing. I could do without it, but like everything else in the world, this is a two-edged sword. I just can not stand it if something does not work, does not work as it should or I am short of my possibilities. That was very beautiful to observe on the weekend trip to the steam train meeting in Zurich : Nobody else builds such detailed models and the repair list brought back is again quite long. On the one hand because details easily get lost or break and because some functions stopped working as constructed. Of course, you could just continue driving anyway - no capital damage - the my internal perfectionist don't let me sleep. At least it is not as bad as the serial figure "Monk". But for an example: I spent an hour looking in the grass for a stupid lens cap from the camera fallen out of the bag and another half after I lost a brake hose imitation. Both can easily be bought again and costs only a few euros. Any other type would also ask if it makes sense for spending weeks in the workshop to get like 15 hours a bit more comfortable driving. But if I can improve it, I want to improve it.
Well, the advantage of the whole combination is also obvious for the user: If you use something I have built, then it works perfectly and in any conceivable situation and if there is actually a mistake in it (as unavoidable in my software projects) it gets fixed in the shortest time possible. That thread goes through my whole life: either I am always annoyed with a half - functioning botch, and its justs a matter of time of when it stops working and I have to find a correct solution later - or invest the time right from the start for the right solution and have fun from the beginning. Even if the right solution takes more time now. And I get a problem with my time management, because I want to make much more than time is available, but that is stuff for an extra article.
