About eighteen months ago, I decided I wanted a healthier relationship with my smartphone. My phone had become a fixture in every aspect of my life. I kept it on my desk when I worked, in my pocket during meals, and by my bedside when I slept. I brought it with me to church, to the gym, to the bathroom. I realized that there was scarcely a moment in my day or night when this tantalizing device wasn’t within arm’s reach.
