For a long time I have assumed I was a self-preservation type, but realised now that it may not be the case after all. For instance, I really do not care about my physical comfort, safety and security and I ignore my body most of the time. A big example of this is that I have a diet (for weight gain) that is in need of implementation as recommended by a nutritionist, but - to the frustration of people close to me - I have a very difficult time keeping with it and sometimes have shown a complete disregard and disinterest in it all together. This sort of thing just isn't normally of any importance usually. I don't look after myself very well.
It also annoys me intensely that the vast majority of people settle down, and have boring, mundane jobs because they care about security too much, stagnating away their life. Stagnation is one of my worst nightmares, and that type of lifestyle would be just awful - I'd rather be insecure but do what I enjoy, than secure (financially, physically etc) but with the drawback of doing activities I hate. What's the point of that, when one only has a single chance to live?
So after some thought, Sp doesn't seem that likely, even if some of the behavioral stereotypes fit. But I cannot figure out which other would replace it. Both could, to be honest. I live to work - but what I want to do and what interests me, and at some point would like to release it into the world to add something to human knowledge/achievement. That seems kind of like Soc. But I can also see Sx needing a situation that completes them and wanting the intensity, because the mundanity of the average life just won't do it.
Anyway, is there any ways that would help me figure out which one fits the best? Perhaps a question or two, or source to some particularly accurate descriptions. Also, if it is possible to tell, is there any variant that sticks out for me?
