I used Newport's recommendations to reclaim 4+ solid hours of deep focus and it's had a tremendous impact on my productivity and general quality of life.
Here are a few strategies I found successful:
* Create a TODO list each day and separate tasks into shallow and deep categories
* Block off each hour of the day and and fill it with one of the TODO items
* Restrict shallow work to 2 hours (after 2 hours, say no to everything shallow)
* Create a scorecard and track the number of deep hours each day (this number should increase)
* Experiment with Newport's recommendations for two weeks and see which ones increase your deep hours
* Become comfortable saying no
