i'm not much good at moving on, either.
but i did love pep rallies!
anyway.
ExFx good things in my experience:
cheering people up, inspiring, motivating, being emotional support, encouraging unity (sometimes
enforcing unity), being a trailblazing/troubleshooting leader, very calm when others are having emotional crises, reading "atmosphere" of a group, skilled at cross-communication / translation / mediation, very often externally feeling-engaged, ease of reading individuals and quickly adapting to their emotional states.
ExFx bad things in my experience:
getting lonely easily, needing external engagement to get out of an emotional funk, getting really wound up after more than a day or so without human interaction, being overly demonstrative when i get
really angry (the fabled ENFP "Te attack"), that awful empty feeling after the party's over and you're driving home alone (probably ExFP-specific).
