I've gained even more respect and understanding for my ESTJ mom (plus others... I've found I enjoy/have enjoyed the company of ESTJs a lot...).
I had major blind spots illuminated by the INTPs on the board. I had no idea how they perceived ENFJs. I was astonished, really. I had no idea that we could be scary to them and that Fe was this nasty fire-breathing beast.
Overall, a greater understanding of everyone that continues to fuel my on-going curiosity. And I'm hopelessly curious, so this could go on forever.
