In the office that I use at work, there's a paper pinned to the wall that says something to this effect: "Multitasking is not effective. Laser-like focus is what makes winners, winners."
I've looked at this poster several times during my shift at work, but haven't thought much of it until recently.
Matthew B. James recently wrote an article for the Huffington Post, about the very thing that the piece of paper in my office talks about. And, as it turns out, that piece of paper is right!
The main premise of his article is that if your mind and body are devided between several tasks at once, you won't be as effective as if you were focusing on one specific task. It really is a simple yet powerful concept. When our brains are engaging in multiple things at once, our consciousnesses are scattered, so we cannot give a task the full amount of attention it is due. Dr. James captures this idea prefectly when he says, "You get what you give. So, if you invest 40 percent, it should be no surprise you get only 40 percent of the result you're seeking."
So if you want to start doing a better job at work, try devoting yourself to one task at a time instead of allowing yourself to get spread thin. Chances are you'll notice your productivity and the quality of your work, go up!
