You know, funnily enough, as someone who considers themselves to have a good memory, I cannot for the life of me remember most meetings, or most conversations for that matter in any sort of verbatim.
What I do focus on is remembering key details, as well as key emotional responses and postures. I try to take away from any sort of interaction any 1) new details that I find to be important and 2) how they reacted to other bits of information.
This helps me create a sort of holistic picture of a person, which I then take with me to my next interaction with them. I find this ultimately more useful than remembering the actual things said, as for the most part the counterparty does not either. However, their fundamental emotional posture(s) and motivations rarely change that quickly and having that knowledge helps me shape conversation faster and better.
