I like the suggestion here:
Two months into 2011, The New York Times tech reporter (and former Wired reporter Jenna Wortham) wrote excitedly that she had finally finished her first e-book — how is such technological tardiness possible for someone so plugged in? Wortham had an excellent explanation: She kept forgetting to pick up any e-book she had started reading. It took the solemn determination of a New Year’s resolution to break that spell.
E-books don’t exist in your peripheral vision. They do not taunt you to finish what you started. They do not serve as constant, embarrassing reminders to your poor reading habits. Even 1,001 digital books are out of sight, and thus out of mind. A possible solution? Notifications that pop up to remind you that you’ve been on page 47 of A Shore Thing for 17 days.
I’m not sure about this, but it feels like I start-and-fail-to-finish more e-books than paper books.
