Would an ENTJ still be an ENTJ if he changed his offensive habits and became more laid back? I think that'd make for an INTP, as I think they and ENTP's are normally the most laid back and cool people out there.
I guess this has been talked over through and through, ENTJ with sugarcoating can approach any type in how laid back they are, and easy going. At least for me, I'm seeing a window in my situation for alternate behavior; I know I can avoid burnout, for example, by really tuning in to the feelings of the moment and really being laid back. If I've set up the time for it and I know I can do it, I can let myself go and enjoy it. Should the prequisites for such opportunity go away, I would start acting in a determined manner.
There are many kinds of chores to do. Some of them can be done with apparent determination, others need pleasing someone. For example, making everyone enjoy in a social situation. I love it, it's fun - it's just that I would not get into a loop of always being the funny man and neglecting my duties.
I think an effective ENTJ can act situationally to meet the needs of the situation, so that the grand plan is rock hard, while the appearance of the ENTJ might not be.
Balanced ENTJ can actually seem and feel pleasant while they're doing their duties, for the benefit of everyone around them, and themselves, too.
