How far can you "push" you tertiary and inferior?
Doing so too much would of course cause great stress and is probably not advisable, but what are the "limits" on personality, as it were? Is there a point where your last two functions just can't develop anymore? What about the secondary, for that matter? Can it "rise" to be almost equal to the dominant or is it stuck as a slave? Would working on your tertiary/inferior diminish your first two in any way, or would it strengthen them because they have more of a base? How exactly does one go about purposely developing them anyway???
