I'm a teacher and there are so many little things to do that pop up unexpectedly in my work. TickTick has helped ease the mental load of remembering them all, and it's more useful than a paper list as your phone is always handy. I think I even sleep better because I have less stress about keeping up with tasks. It's easy to reschedule tasks that you don't get to on a given day. I also enjoy the habit-forming function!
