You may be thinking, “You don’t understand. I live in New York City. My apartment is the size of a smartphone. I need each room to play multiple roles.” Fair enough. If your space is limited, divide your room into activity zones: a chair for reading, a desk for writing, a table for eating. You can do the same with your digital spaces. I know a writer who uses his computer only for writing, his tablet only for reading, and his phone only for social media and texting. Every habit should have a home.
