I store my tasks digitally but work on paper
This may be weird to a lot of people
But most of my lists starts in a notebook. Then I end up in a task app, where they at some point get a due date. At that point it will most of the time end up in a notebook, usually a Rhodia Dotpad if its work or typically my hobo if its not. And at the end of the day or a page I complete what was done in my task app.
The main reason I do it like this is that I find it much easier to think on paper. I can just sit down and write down everything, then move it into a computer. And when I are working I find it much less distracting to have a notebook next to my keyboard than having to change between what I am doing and a task app.
