Looking back on my history with each approach only one thing is clear - I make good use of an approach for a period of time, and then I move onto something else.
The last six months I was all over Trello, using it every day for managing my tasks and ensuring I was only working on one thing at a time.
Right now I have in front of my desk, written on an A4 piece of paper, my mission critical projects for the quarter, some sub-projects outlined for the month, and then activities from those sub-projects that I am going to do this week.
And I am loving this lofi, pen and paper method. But I am sure that in a few months' time I will be well and truely obsessed by something else, which will be just that little bit better at helping me get the right shit done.
