J would be useful. It would mean I could actually get things done or be organised.
S would sometimes be useful also, but the toggle switch is a good idea, as I need N for my ideas.
Am perfectly fine with T and fine with I, although a little less I might be beneficial.
But I don't want to give up anything I've got and I can't choose. Why can't I just have all functions stored away, and when I enter a situation I pick the ones I need to produce the most desirable outcome?
