A habit I picked up from the format of one person preaching to a meeting room.

Take notes, or barring that use fingers or verbal cues (or other memory palace tricks) to keyword myself to remember the multitude of things I want to bringup or am monitoring to see if they're addressed.

I ended up getting a Remarkable for exactly this reason, and all my poorly scrawled notes ended up being very useful to make sure key thoughts and responses were raised at relevant times.
