Cal Newport's book Deep Work has been circling the blogs I follow for the past year. I finally took the time to read over the summer. It's such an enriching book (I'm still reviewing my notes for it) and in an age of social media distraction I would say it is a must read.
Don't just take my word for it though. Read the words of Julian Summerhayes who has a rightly so put together a worthy post to reflect the content of the book.
