We’re all creatures of habit. Sometimes doing the same thing over and over again can lead to boredom. It can also lead to wanting to be free from the predictable. While I always say it’s best to have a writing schedule, this week try something new (which is also a great way to get ready for NaNoWriMo).
If you write in the mornings, try doing it in the evening. If you write at home, try going to the library or the coffee shop. Write alone…try writing with a group.
Shake things up a little and see if it helps with your motivation.
