This is a discussion on Which Lead Function is the Best/Worst to have? within the Myers Briggs Forum forums, part of the Personality Type Forums category; ...
Se is brilliant for enjoying life and living in the moment, but seems dangerous long term.
Hahaha! Whats Si like as a first function?
Se... Ti... Fi... From my point of view, those 3 would be the worst to have. Se because of poor impulse control, Ti because it would be boring for me to spend so much time analysing stuff for the sake of analysis (I don't have patience) and Fi, because I would go insane having all those feelings and nuances of feelings and all that emotional complexity and feelings weaken me and push me off balance... Nope... no thanks! I'll keep my Te :)
I may be biased but I'd say Fi, just because it's in direct opposition to the working/business world, which you need to be able to settle into in order to, like, survive. Ouch.
Hmm.. I don't really like Fe as a leading function because I hate how Fe-dominants are sometimes overly emotional, attention-seeking, malleable and accommodating to others, sometimes at the expense of good sense.
I also don't like Fi too much as a leading....because subjective feelings/values/personal reality sometimes seem to trump objective reality, for these types, leading to some weird-decision making, IMO.
I guess any leading function can be annoying, really, but those are the ones that irk me the most.
