Do you write your todo list at night for the next day or in the morning?

My To Do list is finished at night for the next day.
But it’s build up and updated through the day.
Working that way, the list will be ready at night and I start off my next day already knowing what to do.

I actually do both. If there is something that I think of at the time for the next day, I will right it down. Then in the morning, I already have some ideas ready to go and once again add as I think of things to do.

It depends. When I have much free time I write my to do list for a couple of following days (if possible).
But of course I also have daily morning routine to do list written down once and forever.
