I don't know what to do about my Frankenthread.
Share a common penchant for abstraction and exploring the pervasive generalities of life. Differ in general in the style and content of those generalities....generally .
Share many of the same interests and activities and a penchant for making things and excelling at whatever it is we are doing. Differ in the degree of detail, and concrete attention paid to what is being done.
Fellow work-a-holics. Both can loose perspective on our work and have it take a life of its own. Share perfectionist tendencies, but can be counted on to regularly aim and achieve the "best" in class or company or group. When I looked at who had the highest grades in college, or the best specs. on design projects they tended to be other NTs or SJs--I was an engineering/math major. Differ, however, in how much we "carried forward." Seemed like SJs were focus more on the current project and much less on what was needed in the future.
