The way I personally use it may differ from my other coworkers, but there's a heading for each day. I start the day by copying everything up from the previous day that wasn't completed, then I prioritize the bullet points and highlight what I hope to finish that day. Each week has an "accomplishments" header that is used at review time. I choose what goes there. My boss rarely adds things other than just prior to our one on one so he doesn't forget. Having a running daily Todo that begins as a copy of yesterday's mind map makes focus so much easier. Then when I have a status update that I don't want to disturb his busy schedule with, I tag him in a document comment or assign a task. I can message or email for urgent needs, but this is a lower percentage occurrence. Hope that gives some insight. Happy to answer any other questions.
Just to provide the opposite perspective, that sounds like my hell. A weekly catch-up, fine, and the rest of the time if I have anything worth chatting about I will. I can't stand the ritual ceremonies.
