I’ve tried a lot of task managers. Todoist was the first task manager I used, back in 2015. I was very happy with it, got premium, but stopped using it about 1½ years later — so what happened?
The answer is rather simple; I got overwhelmed. Not by Todoist, but by the tasks. It may seem counter-intuitive to stop using a task manager when the tasks become overwhelming — and it is. Instead of tackling the growing number of tasks, I convinced myself that the problem was the tool; Todoist.
