A few summers back I was working as an AuPair in Spain. I was robbed of my phone the first weekend I was there. I spent the next five weeks in a foreign country, with limited language skills, and no phone - and it was one of the best experiences of my life. I felt so refreshed when I came back to the states. Really like your idea of disconnecting on Sundays and moreover, starting a newsletter to record how you spend that time - think that's a great way to inspire others to do the same. Solid piece, always enjoy reading your work.
