I can be like LSI, but it's been years since I've been like that. I'm a lot more settled in to being relaxed like the SLI, but I can't deny the asshole streak. I always chalked it up as just a phase. I had to be on the defensive a lot growing up, so eventually I decided to be offensive. I kind of lost it for awhile. A lot of my friends thought I was going to get killed, because I was too cocky for my own good. And generally speaking, I'm an impatient person at the very least. It sounds like LSI-Se.
In socionics, Se for SLIs is in the "id block".. it's an unconscious side.
"SLIs try to avoid making demands on others and themselves and prefer to motivate people by offering them enjoyable rewards rather than pressuring them to act. They are impervious to forceful attempts by others to make them do things and become very stubborn when pressured. However, when under extreme stress or in a hostile situation, SLIs can become very aggressive and forceful for periods― sometimes with malicious intent. This function is the strongest (and malevolent) part of the SLIs' subconscious."
I could chalk it up to this, I guess. I still think the definitions are iffy though. It's like the MBTI definitions have been split up, where Si and Se in socionics have a little bit of each other in them.
Mechanic fits the best out of those. My job title is Application Developer Consultant so Nerd fits pretty good as well. I am a little out of practice, but does being a black belt make me anytype of jock? I am a bum as well on my spare time. Im not a daredevil, i just like to push myself so i can do stupid crap safely.
Take what I say with a grain of salt, because that's all it is compared to the ocean of complexity when it comes to actions and real life.
