Hmm, has knowing your MBTI helped you though? I did a couple similar exercises in the past at work. It felt like a great revelation at first, but I always forgot about it soon after and stuck to how I was.
Right, do you mind expanding on this? I'm curious but I struggle to understand. Maybe if you have an example that might help.
However, the way I think about it is that people respond better to different way of communication, and knowing a person's preferred styled of communication will be helpful in helping a person open up and get to the root of issue.
