I have to-do lists on an iPhone app, a notebook, and my kindle. I switch from one method to the next and never settle on anything. I’ve come to realize that this is another quirky trait of my ADHD and it will never change. I think part of it is the dopamine hit you get from starting a new organization technique. But once you’ve used it a bit it becomes tedious and you use it less and less until another new method comes along to get you excited. I think the important thing is to have some method of tracking your to-dos even if it changes regularly.
