Make each of your actions a completed task so you can move on to something else. That’s a simple idea, and in fact it is what every moment of one’s life is, because every moment builds on the previous one. The idea is more general when the word “task” is added because that encompasses more than just the events embedded in the moments in the passage of time; it implies a goal which is made up of multiple tasks.
Usually the tasks will have a natural sequence, such as you must wash the dishes before you dry them, and must dry them before you put them in their cabinet. If your goal is to get the dishes cleaned and put away, and you stop after washing half of the dishes, there remains an anxiety hovering in your mind, because of the mess that will remain in the sink. A half-done task will mentally interfere with other things you would prefer to be doing. By stopping in mid-task you make the rest of your day more complicated. You must work around the messy part, which makes whatever task you are doing later less efficient, and that new task takes longer and can’t be done as well.
By making each of your tasks a completed action, you free up all of the actions you do for the rest of the day, and you can do a better job of giving them your full attention. During the course of a day you will perform many tasks, but if each of them were only half done, or poorly done, then each would leave a trail of clutter, and would require workaround catch-ups. The trail of half-done tasks would grow, and complicated-messes would occur because of the overlapping of the existing simple-messes.
This idea is applicable to every task you do, not just household tasks, so:
Make each of your actions a completed task so you can give your full attention to your next task.
