Info from my MBTI type thread.
I am very contemplative, analytical, and perfectionistic. I'm not openly competitive, but I hate losing. I can be vocally and stubbornly opinionated, though I also have a tendency to let others think for me. I'm fairly impatient and prone to flash-like tantrums (after the problem is solved, I tend to feel bad for erupting). I'm not that good with doing what I'm told, especially if it doesn't make sense to me. I do what I can to preserve a sense of autonomy in my life. I like being in a position to influence/direct others' behavior, but I'm not fond of responsibility. In general, I prefer people who listen to what I say rather than always talking back or resisting. I would say I'm more consequence-oriented than right/wrong-oriented.
As a child, I was very loud and tended to bounce off the walls. I'm still pretty bouncy sometimes, though my energy levels vary. I need to be constantly doing something, but that 'something' is more likely to be reading, drawing, or surfing the Net than actual physical activity. I generally prepare for outings by bringing books or notebooks so I don't get stuck with nothing to do. I enjoy roleplaying online; make-believe is fun, whatever medium it's in. I'm pretty social in my own way, though I prefer to be the focus of attention.
I'm pretty affectionate if I feel comfortable enough around someone and am sure they won't react badly. I prefer people to whom I can communicate my feelings toward them without scaring them off. I'm also physically affectionate, though more so on the internet.
I hate chores and housework. I'm not fond of "work before play", either. Let me play to my heart's content, and then I might consider working. This doesn't end very well when schoolwork is involved. I know I need to change that; it's just a matter of doing so.
I have a tendency to hold grudges; conversely, I tend to remember friends fondly. On the other hand, I'm horrible about keeping up with old friends. Thank goodness for Facebook. I'm pretty "out of sight, out of mind", both with friends and with my possessions. Speaking of friends and possessions... I'm extremely possessive and quite territorial. My criterion for "mine" tends to be whether I like him/her/it. I feel like I need to ease off on it; it should be OK if my friends have closer friends, or if girls flirt with the guy I like (and am not dating).
I am very creative and imaginative, and I always have been. I'm very inwardly-focused and physically unobservant; however, as a young child (<5), I used to give out directions with street names. This would suggest to me that I'm naturally quite observant, and that the inward focus is probably depression-related (this has been corroborated by a psychologist).
