Great reflection on Cal Newport's book Alex! I really enjoyed reading it. Thanks for putting your thoughts on the paper.
Here are other books that motivated me to use my phone for not more than an hour a day:
Deep Work: Rules for Focused Success in a Distracted World
Indistractable: How to Control Your Attention and Choose Your Life
How to Break Up with your Phone: The 30-Day Plan to Take Back Your Life
Take care:) Looking forward to your next article!
