How many mental activities can you do at the same time? If you answered anything above one, your either superman or you need mental guidance. As that is impossible according to recent studies. You can be chatting with the person next to you, or reading the book in front of you, not both. We fool ourselves thinking were multi-taking by switching from one thing to another quickly. But in reality were also switching focus doing one thing at a time.
There is however one exclusion studies approved. When you do something for so long to the point that your really good at it. Then you can do that and something else both at the same time. Like chatting on your device while walking for instance. Even when multi-tasking in that situation we often don’t scan the environment around us and might bump into something. Making us a lot more lousy then when just doing one task at a time. So if you have lots of time in your hands, just do things
once one at a time.
