Every time I attempt to multitask, I wind up doing each task with a lower level of quality than I would have if I had focused on just that task. My concentration isn’t fully sustained on any of the tasks I juggle, so I wind up using only a slice of my brain for each task. That simply results in lower quality work.
I also wind up investing the same amount of time – or even more – when I multitask. That’s because there’s a brief pause each time I switch my primary concentration between multiple tasks. If I keep switching back and forth, those lost seconds start to really add up.
In the end, I’m left with tasks done in a mediocre fashion and, quite often, no time saved at all. That, to me, is a lose-lose.
