Great article! I first heard about how important single tasking is in a book called "The Organized Mind" by Daniel J. Levitin.

He talks about how our mind works, how we user our brain to do all kind of tasks, how we can avoid stressing ourselves out with useless information and how to avoid forgetting things, and most importantly, why learning how to focus on one thing at a time is way more important than multitasking.

One argument he gives in his book is that when you multitask and you focus on only one task, your entire brain is focused on that task alone and on whatever that task requires.

For example, if you write an article your brain can focus on several activities at a time related to that particular task and nothing more. Your brain will focus on: writing, checking your spelling, thinking about what to write next, when you need to use commas, etc.

However, if you focus on more things at a time, like writing, watching a video, talking to someone or looking at the phone, your brain has to constantly move between tasks and focus its attention on too many things. That leads to fatigue and to poor concentration and, obviously, poor results.

I didn't think it was true until I tried it and I started to achieve the flow state more and more often, being way more productive than before and getting better results overall.

Great article, and I hope more people read it and understand how much they can get by learning how to work on one task at a time.

Another book that tackles the same subject is "Deep Work: Rules for Focused Success in a Distracted World" by Cal Newport. I only had the pleasure to listen to only two chapters (i downloaded the audiobook), but I will surely get back to it when I'll have the time.

Congrats for the article and keep up the good work! :)
