If things turn out differently, ala as you did not expect, then it seems to me you would be better served by being able to do work on the fly to fix things as they need to be so no one gets fired, right?
OK, last point, I am 100% S, my wife is 100% J, and while I am hyper, spastic, and goofy, I am the calm one of the two of us. In a bind, I can act and perform, where she might be a little freaked out and need a minute to regroup, by which time I'm done with the fix and sipping coffee.
And as far as comfort, I am comfortable with all in the here and now as I am comfortable with me, so no matter if things turn out as I expected, try to make happen, or completely different, I am at peace and have coping skills as a result of it.
