The character, not the real life person or the actor. I was just thinking about how people often somewhat mistake what 'quality of life' or 'comfort' mean in relation to of the ESTj. Here's a character that exemplifies that function. The character could be ESFj too, but I call ESTj by the skin of his teeth.

The "fish out of water" phenomenon is particularly illustrative of the 'judicious' trait of 'Si' and a character so openly meddling in people's affairs is certainly not IxxP.

The 'quality of life' and 'comfort' is whatever the person has mastered and gotten used to.
