Deep Work by Cal Newport (англ)

One of the most valuable skills in our economy is becoming increasingly rare. If you master this skill, you'll achieve extraordinary results.
Deep Work is an indispensable guide to anyone seeking focused success in a distracted world.
'Cal Newport is exceptional in the realm of self-help authors' New York Times

'Deep work' is the ability to focus without distraction on a cognitively demanding task. Coined by author and professor Cal Newport on his popular blog Study Hacks, deep work will make you better at what you do, let you achieve more in less time and provide the sense of true fulfilment that comes from the mastery of a skill. In short, deep work is like a superpower in our increasingly competitive economy.
And yet most people, whether knowledge workers in noisy open-plan offices or creatives struggling to sharpen their vision, have lost the ability to go deep - spending their days instead in a frantic blur of email and social media, not even realising there's a better way.
