I use onenote with my own crappy markdown to prevent onenote from being "helpful" I do week plans with stuff for the week on top and meetings below . I used to do daily but the issue was that unless I read through each day for the week again nothing stuck. Format is as follows
Week of May 31

it's working much better and ensures I don't forget things. Review previous week on Mon and pull tasks forward and provide any critical feedback as required.
Also an old boss C-level IT printed his daily agenda on an A4 and then noted in meetings against that. I don't have access to a printer but I appreciated the simplicity and that it made the attendees feel like they were getting proper attention as he didn't bring a computer in at all.
