But I'd like to caution people here who are impressed with my system that in the past, I too have been very impressed by other people's planning systems. I have tried a bunch of systems and tools that have worked for others - GTD, Pomodoro, Mind mapping, Trello, Kanban. But they did not work for me, often for minor reasons. The problem was not with those systems, but with my mind. Understanding how my own brain works, knowing its quirks, and using something that gets out of the way is how I got here. Text files and simple command-line tools work and even motivate me, but may not work or motivate somebody else. I'd suggest focussing on knowing your own quirks, and on ways you know can improve your self-discipline. The tools are usually not the root problem.
