If you want to tip the daily balance from shallow work to deep work, my buddy Curtis in British Columbia recommends Cal Newport's book, Deep Work.

In Deep Work, Cal Newport wants to convince us to step away from the ever-increasing series of distractions — those latest and greatest things that pull away our focus and keep us from doing deep work. Newport doesn’t just stop in telling us that distraction is harming us, but goes on to give us four rules to achieve a state of deep work with more regularity so that we can truly produce work that’s industry leading (without working evenings and weekends).

— Accomplish more of worth and suffer from less distraction: Deep Work by Cal Newport by Curtis McHale

Going by Curtis' review (and the fact I highly value his recommendations), I'm definitely adding this book to my reading list.
