Thanks for the great question. I would say that the primary approach to dealing with any kind of anxiety is to welcome it and face it head-on. Dive in and experience what’s actually true, the true amount of forgetting, and the true repercussions of the forgetting. It’s all always much less bad in reality than the anxiety claims it is.
Secondly, I do use a system based on AirTable to track all my meetings, just for my own memory. I can store information there about people and meetings. I don’t use it that aspect much through.
Since I meet with so many people, I do often forget all kinds of things such as whether or when I already met someone or details about their work or their life. I have discovered that it’s not really a problem, and it’s an opportunity to apologize and learn again and more deeply. Nobody is offended by good intentions, which you clearly have.
