Good article, staying organised is most definitely an important factor, it is so easy to get overwhelmed if you don't know which task to start. I do find lists useful to a point but in my line of work that list can grow from a handful of tasks up to over 20 within a matter of hours. I always try to list any additional work as tasks for tomorrow but find putting a little priority/importance measure against tasks very very useful because 20 tasks can be too much to mentally handle but 5 important tasks and 15 tasks which are either menial or not urgent can be kept separate so that your mind can focus on the pressing issues.
