Meanwhile, an activity that uses your body and mind, like writing or full-out exercise, should be done alone.

Most importantly, every single person has a best way of doing things for themselves. I’m a life-long multitasker (from long before I ever heard the term) while one of my best friends can’t do it at all, neither of us is wrong because we use the right approach for us.

There have also been a few neurological studies that suggest that men and women are wired differently in this area. Women have evolved to multitask because, traditionally, we have no choice if we have children to care for on top of our long list of other responsibilities (remember, this is the past) like cooking different parts of a meal and cleaning while we go. Men have evolved to singletask because it made them better hunters. I’m not a neurologist but that makes a LOT of sense, anthropologically speaking and by watching how the people I know work as well.

Now, for the tips you have mentioned, only one tab and only one screen, I don’t really see how that is supposed to help. I don’t use multiple monitors because I don’t really require it but I would never be able to work with only one tab. I don’t see why I should either, it would really just slow me down.

I would say tackle one task at a time, because it feels great to be on top of things and feel like you have actually accomplished what you were supposed to every time you finish a task, but use as many tabs and screens as you need to if it makes you more efficient, which it usually would do.
