Entrepreneurs are masters of multi-tasking… or so we think. I have come to realize that I’m kidding myself. I’m not an effective multi-tasker, just a bit AD..squirrel! For those of us that need to get stuff done, Deep Work, Rules for Focused Success in a Distracted World, by Cal Newport, discusses the research on our misbelief that we can successfully multi-task. It also offers some great insights on ways we can create more opportunities for the quality work that comes from getting into the zone. 
From creating a set time for your work that requires an uninterrupted, undistracted work, to taking time for moving meditation (letting your mind work on a specific problem while performing repetitive tasks such as walking the dog, biking to work, etc.), Deep work will help you start to change your daily routines so that you can achieve the quality work you are hoping for.
I have started to implement some of the techniques described in the book and it’s already helped me finish up a couple of projects that have been nagging at me. Definitely worth the read.
