I heard someone say the other day there’s no such thing as multi-tasking.
What this phenomenon is – “doing several things at once” – is really a constant shifting of attention from one project to another. One moment this item has your full attention, and the next moment that item has your full attention, and the moment after that an entirely different item is on your radar screen. Then you rotate around and this item has your full attention again, then that item and the entirely different item, and so on.
But is it your full attention? It takes a while to get into a rhythm on any task. Do you really get fully into that rhythm before you stop abruptly and work on something else? Would you be better served by focusing entirely on the first item until it is completely addressed, then moving on to the second one, and then the third?
Because you don’t have the time taken in the constant start-and-stop of momentum to deal with, perhaps it would be more efficient to “single task” the to-do list. Allot time to each of the tasks, but work them one at a time rather than “all at once.” The way the brain works, you’re really doing them all one at a time anyway, but with a scattered focus.
I suspect Curly in City Slickers had it right: The ultimate secret is: “One thing. Just one thing.”
