As a life long fan of lists (but paradoxically - not to-do lists), I like this advice: Be a schedule builder not a to-do list maker!
I aim to limit my must dos in my diary from zero to three each day. But I am a creature of habit and I do like schedules. I still like to use a printed one-page-a-day diary instead of a a digital one, and I still like to set up the week on a Sunday. Our school uses a ten day timetable so if I'm feeling particularly crazy I do my schedule for those ten days.
This works for me - it may not work for you!
Things like my teaching timetable, regular zoom meetings, face to face meetings, duty slots, times for doing my weekly reports, appointments, Learning Centre supervisions, and regular student meetings are put onto my schedule.
I like to physically write them down each week (rather than set them up digitally as recurring events) because they then lodge in my brain (hence the, mostly, one week version rather than the ten day one).
As I indicated in my previous post, I'm time poor. That means my schedule is pretty full with stuff and I sometines have to double book myself (a zoom meeting while doing a supervision is reasonably common).
If I was to do a to-do list each day I wold probably explode. So I don't.
But I do recommend the scheduling approach.
