My understanding of breeding roses/flowers is limited, but it seems to me that it would require regular attention to minute variations of their physical properties, as well as a clear understanding of how to manipulate those properties for future generations. This suggests to me a strong possibility for dynamic type and Se valuing. This can also be used when fitting a bed frame, etc. But then, Si creative has Se demonstrative, so it could be that as well. Either way...Se info about properties of objects, as well as having the will to alter your environment according to how you want it, suggests a heavy Se focus. (not ds, ignoring, polr, nor role... Leaving Se as base, creative, hidden agenda, or demonstrative...SeXi, XiSe, and any of the EJs.) It's certainly not something you spend time on only when pressured to do so...and then revert to a more comfortable mode of processing as soon as the pressure lightens.
Often, your pictures remind me of the ones that @cracka takes and posts. Both in attention to scenery, but also a high focus on personal interest...his cars, yours roses. I can actually see you and cracka as being quite similar...minus the enneagram differences. (certainly more so than I can see a similarity between you and Director Abbie or Expat.)
I can't think of any particular polr you might have. Whatever it is, it doesn't particularly call out. I think perhaps your E6ness aids you in not showing your weaknesses, as would the circumstances behind the ptsd.
Lets see...I believe Extrovert, because you seem comfortable manipulating real objects, feelings, emotions, and sensations...and rarely discuss your imaginings and reflections. You also seem to be more focused on how objects interact with each other, rather than interpreting everything as relating to yourself.
I also think you are a Rational type. I think you find it easy to first assess incoming information before responding, rather than taking the info in and responding to it, before assessing it.
Extrovert Rational puts you at any EJ.
I think you might be Decisive>Reasonable...but I'm not really sure. You've always struck me as someone who's usually in a mobilized state rather than a relaxed one. You certainly don't seem to need external motivation to get yourself moving, which reasonable types are said to need. EIE/LIE are both Decisive EJs.
And I think you might be Subjective>Objective...but again, I'm not really sure. It seems to me that you consider the source of the information as being important to how much consideration you give it. And that of higher importance is your subjective view of a situation...(even if you might reconsider over time). ESE/EIE are both Subjective EJs.
If I were forced to type you at this moment...I would suggest EIE based on the above.
But I'd prefer to see what you think of these ideas first.
