Thank you five sounds for these hands-on strategies!
I very much appreciate the company of ESTPs and ENFPs - I often feel that they complete me, cover my back and help me in the outside world and vice versa! ESFPs I don't know - I'll think about that.
Now regarding "If you are actually INFJ" I can't help my Don Quixote-tendencies from surfacing

Beebe stack for INFJ (Ni-Fe-Ti-Se-Ne-Fi-Te-Si):
Hero Ni:
I love (become obsessed with) coming to closure and getting to the botton with problem solving even if I constantly feel very insecure of what I'm actually doing. Understanding the logic (Ti) is very strenouos to me but juggling with the symbolics usually brings me up from the basement with some gems in the end

Good parent Fe:
I am a coward when it comes to giving critique and I put the harmony of the group above everything else, unless there is something really important (from my view) at stake.
Eternal child Ti:
I love designing those little (overly-)simplifed mathematical toys (using well-established physical laws such as Newton's and energy conservation - no true innovation there) to help my fellow colleagues and clients at work. In that respect I probably spent my entire career (applied research and engineering consultancy) playing innocent games in that sense

Animus Se:
This is very much my Achilles heel - when under stress I completely ignore my bodily needs in terms of sleep etc. I smoke, drink, eat whatever my instinct urges me to. Dancing and music (EBM and crossover such as Slayer, Nine Inch Nails, Front 242 etc - but due to obvious age-related pathetical reasons not any longer

) can put me in some sort of trance-like state. The same goes for down-hill skiing (not yet embarrasing

) and, yes I admit, sex.
Opposing personality / opposite gender Ne:
I can get really annoyed (probably visibly) when people are brain-storming endlessly around me when I just want to come to closure on a subject. In new social settings i probably come off as pretty stereotypelike-feminine, gossiping and chatting about mundane matters that usually holds no particular interest to me otherwise.
Senex / bad parent Fi:
I quit work twice because of extreme dislike of a narrow-minded profit-driven agenda high up in the hierarchy (I hope they didn't read my work assessment form for my own sake

). I can be very rigid and blaming on my children when they behave selfishly, bringing up topics such as "consider the children in Africa" when they don't want to finish their meals etc. Only to feel bad and guilty afterwards. For good reasons.
Trickster / bad child Te:
I can become furious (in written correspondence) when banks etc try to bind me with fine print text where they as usual put all responsibility and all risk on the customer and double-bind them with their own formulations, usually in combination with harsh moral passages a-la Fi above.
Demon / daimon Si: When under (extreme) stress I become obsessed with organizing, sorting and throwing items from the past. Interior decoration, optimising furniture placement. Isolation. Just to transform the environment to something familiar and predictable. Minimising external input from Se and Fe just to be able to sort things out in my head and get a new fresh start and put things behind me.
