As an undergraduate, I commuted to college and was able to maintain some distance between work and home. Now that I live on campus, these two worlds are increasingly intertwined. Emails flow in at all hours on a multitude of projects. Peers must be communicated with or progress stalls. Some people really never turn their phone off. They allow themselves to be interrupted constantly from whatever it is they’re doing, thinking, even saying. This kills writing.
To write, one must be solitary. Alone with a pen and a story, and alone with nothing to do but wonder about your characters and think of the tales you have to tell. Social media and other phone-based gadgets have become space-fillers. Once upon a time (15 years ago), people had blank space in their lives. Waiting in line. Riding a bus. Watching a pot that won’t boil. Those blank spaces are when the mind gets back in touch with itself, and starts wandering through stories. They’re important for writing.
Writers shouldn’t be alone all the time or even most of the time, but they need to have time to process ideas. If you don’t have it, make it. Take a moment to unhook and unwind, and consider what’s important to you. Then, write about it!
