I remember coming across something that said intuitives are introspective types... which I would have thought was more of an introverted thing to do, but it makes sense, introspection means observing your thoughts from outside of yourself, if a sensor is living in the real world (be it here and now, or the past) would they introspect much?
So basically... how do you introspect? Where do you introspect? What do you discover from introspection, and has it been useful? I remember richard feynman was quite introspective
How?
I kind of latch on a stream of consciousness. Since Ni is both a perceiving function and introverted, it can feed off of itself to find different connections and insights.
Where?
I usually pace back and forth a short distance, it helps keep my mind 'stretched' enough to not get stuck on one thought too long. Sometimes I lay on a comfortable couch or in bed. For that reason, I enjoy waking up in the middle of the night, I'm full of creative thoughts then.
What?
Usually what I need to work on to improve myself, how to do that, and trying to 'find who I am.' Sometimes it is just a lot of odd ideas related to certain topics, and since I've been hooked on the Final Fantasy VII story and characters, many of my thoughts revolve around that. Mentally 'playing' with the characters and how they act better helps me understand them. Maybe I should apply it to real life people too.
Usefulness?
It helps me recover from being social for a long time, because my main functions that work when I'm being social is Se and Fe. Ni is turned off until I'm alone again. I'm not usually the quiet one in a conversation because I like to be actively involved in it (Usually by making jokes).
And when I am depressed, if I find a good train of thought I can find the right perspective of the problem and then understand what it takes to fix it. The most frustrating part in this situation, though, is that I tend to be 'fishing in mud' mentally and if feels like I can't catch anything. But then suddenly an epiphany sparks in my mind and then everything I was worrying about makes sense. ('Skyward gains +1 to Wisdom!')
