I realized I was setting arbitrary due dates on my todo list as a way to prioritize tasks so they'd show up in order of importance, but it turns out that's a terrible technique.
I just did a major refactoring of my Todoist and now I'm using priority 1/2/3 tags for that, and due dates only when a task is really due that day.
I'm still figuring out exactly how to use the priorities, here's what I've got so far:
• p1 - this is top priority, I should do things in this list as soon as possible
• p2 - things that I want top of mind, but can wait until things in p1 are done
• p3 - sort of a catch-all when I want something to bubble up a bit quicker than if it has no priority tag
I also switched my main view in Todoist to a custom filter that shows me:
• tasks due today
• priority 1 tasks not due today
• overdue tasks
I'm going to try to stick to this view as my primary view instead of clicking on the "Today" tab.
