@Mane Interesting. I need to think this through.
Never really considered 7 and I can't say that I particularly relate to feeling "deprived". However, the idea of finally finding satisfaction in a future plan (planning as a tool to keep the good feelings) does resonate strongly as well as gluttony (not food necessarily but any experience to delay the difficult). Also, getting scattered is something that I work against and I have realised that I have to reign in in order to grow. Furthermore, the 7s view of egalitarian power distribution in order not to be controlled by any body else's whims also makes sense. Being "limited" is definitely a scary thing.
However, none of the typical 7 behaviours really apply. Spontaneity, center of attention, extraversion, etc. do not resonate.
(There is little in the 8 description that really fits because of their unequivocal assertiveness, decisiveness and authoritativeness as well as their need to be stronger than others).
