I'm usually in a mental state not unlike daydreaming, oblivious to my surroundings.
I avoid contact with strangers -- and people in general -- when I can.
When forced to deal with people, I am cordial with friends, formal with acquaintances, and ignorant of strangers.
I spend most of my time thinking about things that don't actually exist in reality, such as elements from my fictional universe. If I'm thinking about anything in the here-and-now, it usually has something to do with computer programming or some other solitary creative hobby.
I tend to ruminate more often than I reach conclusions, which is part of the reason why I stay quiet until I'm sure of what I want to say.
Astrologically, I'm a Libra.
Let's see, what is that supposed to say about me?
Good
Not so good
No wonder I can't get anything done.
INTP: Rational/Architect
I am an INTP. What that stands for is : Introverted iNtuitive Thinking Perciever.
Keirsey's "Architect"
According to the Keirsey/MBTI personality science categories I'm a "Rational/Architect", which means:
Wow, that was pretty flattering. Lets try it the other way.
INTP Under Stress
According to a few sources on the internet:
INTPs lack follow-through and this can isolate their ideas from practical examination. Their notions become over-intellectualized and too abstract to be of practical benefit. With their sharp critical thinking and analytical abilities, INTPs tend to nit-pick, hair-split, and generally overdo simple issues. Their desire for accuracy and precision exacerbates any error they may perceive in themselves or in others — they are, in other words, highly self-critical. Wanting to be competent and know everything, their standards grow increasingly higher. When fear of failing becomes overly pronounced, INTPs are quick to feel unintelligent, slow, and powerless.
If stress continues, the INTP's mind seems to freeze and block out the vital information it has worked so hard to accumulate. Their creative juices stop flowing and they suffer from stage fright, writers block, and a general inhibition of their ingenious thinking and fluent language skills. Preoccupied with performance failure, INTPs become self-consciously distracted in anticipation of their failure. If the stress becomes too overwhelming, the fear of blanking out prevents them from taking risks in areas they desire to succeed in. Attempting to avoid incompetence, they fail to gain the expertise and mastery they so desperately need.
