So, while at work, I decided to try to get to know my ENTJ-self a little bit better...here's what I found:
Careers for the NT "Rationals" (INTP, ENTP, INTJ, ENTJ)Rationals are natural born scientists and engineers, and are referred to as "the knowledge seeking" person. Many ADD Rationals
do OK in school (but may underachieve) and they often go on to college. One ENTP has a webpage which says something like "I quit high school to play in a rock band, and later went to Yale to study physics." NTs judge themselves based on their ability to perform (whether it be getting things done or coming up with solutions) and are therefore unusually prone to performance anxiety. ADD probably increases the chance of this happening, since it can interfere with the ability to get things done.
Be aware: once a subject is mastered, the NT is likely to move on. This is true even for NTs who are not ADD. Figure this into your thinking. Are there future lateral career moves you can make to maintain interest? A related, but somewhat different career? A different type of company to work for? Don't berate yourself because you put so much energy into becoming good at what you do, only to find yourself oddly depressed with your job. Expect it to happen and plan for it. Use your love of logic to figure out a chain of possible career or job moves rather than expecting to find one and stick to it.
In "Please Understand Me," David Keirsey says that "his early start and his persistence enable the NT to excel above the other styles in technology. And, as the intellectual ability of the NT increases, the tendency to seek the sciences, mathematics, philosophy, architecture, engineering -- indeed, anything complicated and exacting -- also increases. These occupations, therefore, are heavily populated by NTs."
An NT child with ADD might learn to dislike school and not go on to college. But of all types, the NTs probably benefit most from college, because an advanced degree allows them to pursue the complex subjects which interest them most.
The worst career for an NT is one involving routine, excessive rules, boredom, simplicity.
NTs are known for breaking any rule which is illogical and which interferes with getting the job done. NTs are full of ideas. A career which does not allow the NT to utilize their creativity will soon become frustrating and boring.
Some more specifics from "Please Understand Me":
"ENTJs will usually rise to positions of responsibility and enjoy being executives."
"ENTPs are good at innovative projects and can administer them well if dull routine is not involved. They usually are outstanding teachers, continuously devising new participative ways to make learning exciting for the students."
"The INTP is the architect of a system and leaves it to others to be the builder and the applicator...They are, however, often excellent teachers, particularly for advanced students, although INTPs do not always enjoy much popularity, for they can be hard taskmasters."
INTJs "can be outstanding in scientific research and also outstanding as executives who generate a plethora of implementations of ideas."
The NT ADDer: In general, careers which are good for an NT are also good for an NT which is ADD. The specific setting or job is likely to make a difference. For example, a large company with a lot of red tape may be unbearable to a particular NT/ADD engineer, while starting up business might be quite satisfying. There are science jobs involving research and science jobs involving tons of paperwork. The real trick is in avoiding the job with lots of paperwork (or at least delegating that part of the job).
