Manageable ones! It can be longer if it includes lots of little things, but shorter if tasks are harder or take longer to complete
I like longer ones because it gives me something to do if I get board. So when I am board I can look at my list and find something productive to do.
I’ve done long lists for years, and recently shifted to a shorter, more focused list – and I’m getting much more accomplished every day!
I think shorter but more meaningful. If the list is prioritised I think it helps & provides a sense of achievement. If the list is extensive it can be a distraction of loads of things that aren’t meaningful but just general to do things that would be a part of a normal day anyway. I write my priority to do list & complete a 2nd list with the less important tasks that I will set aside an hour to get through as many of them as possible. Those that I dont get through in the hour I will leave until the next hour tmro.
