Type dynamics: changes that happen as you age and (hopefully) mature. For example, why your ISFJ spouse suddenly gets fixed on philosophy at age 40.
Better understanding of stressers and how you might react to temporary and chronic stress. (And how others might, so you can better work with them.)
Better appreciation for your unexpected strengths and awareness of unexpected weaknesses. For example, as an INTP, have you developed Feeling-function skills or Extraverted Thinking skills--these are skills that would not be expected in a typical INTP. Or, as an INTP, are your Introverted Thinking skills of logical analysis unexpectedly weak?
Better ability to communicate to different audiences. Are you engaging and interesting to people who are not like you? (Great thing about INXXs--most everyone isn't like us, so we get a lot of opportunities to practice

)
Better appreciation of how others view things. Honestly, I am amazed that my ISFJ husband can be in the moment and aware of details without the symbolism that my iNtuiting perception snags. He always notices things like if the milk is going sour. I don't.
Humility and wonder at it all. Type, the diversity of humanity, the flexibility of the mind, the Type/MBTI system itself. For when you Ti/Ne off, anyway.
