When you are overwhelmed with work, you might schedule too much in one day, in the wishful hope that you will magically get it all done. This is a false and unfair promise. It is not how much you get done, but whether you are doing what is essential toward a long-term goal.
If I can reach only one goal today, which one will take me closest to where I want to be?
Write one goal and do it. By choosing your course of action one at a time, you can decide what to do next using the most current information.
Concentrate on your task and do not allow yourself to be distracted for ten minutes. Then take a rest.
Don’t worry about choosing goals that are modest. Pick something you can finish. Involve other people to stay on track.
