Fun little exercise. Can be as long or as short as you want.
Introverted Thinking: Reasoning in terms of situational logic. Using Ti, I'm able to analyse every situation in front of me in terms of its individual variables and, as a result, assess the logical coherency of what I'm perceiving. This involves a constant process of categorising and sub-categorising everything, shifting those categories about, until a wonderful logical whole emerges. It's like shifting the pieces of a jigsaw around until you finally see the whole picture.
Extraverted Intuition: Gaining a witty, spontaneous insight - it's kind of like looking through the cracks of a rock surface and finding a wonderful malteser inside, waiting to be devoured. Most of the time it reveals itself via silly wordplay, sometimes it reveals itself in terms of finding new opportunities for something. I might notice something that someone said, assess the logic of the statement, and find an opportunity that allows me to say something witty, and I just can't keep it in and I have to bloody say it or I'll explode. Or I'll swallow it and after a few seconds the moment will pass, and I'll just look like a fool if I say it now after waiting too long.
Introverted Sensation: Internalizing sensations to create a sense of stability. Sensations around me trigger an association with the past, and that could either be a good sensation or a bad sensation. If I'm particuarly stressed out or too tired I can become irritable about new experiences, not wanting to risk damaging or losing the sensations I have stored up (that's the best way I can put it).
Extraverted Feeling: Creating connections and fostering emotional ties with others. I've found that I can get away with minimal social contact with others with my sanity intact. I sometimes avoid social events by saying that "I find time around others to be too distracting or shallow/fickle", but when I do end up being dragged to something I often have an alright time. I know that if I'm left to my own devices for too long I'll cut off all connections with others, and I'll start to turn into "that strange loner" who just plain refuses to leave his Home Sweet Home and humble himself in front of others. That's when things go baaaaad.
