My second baby didn’t sleep during the day unless we were walking her around in her stroller. This meant that I spent hours each week wandering the streets and parks of my neighborhood. Not so conducive to writing. So, instead I tried to keep my brain alive by listening to audio books. There are so many amazing audio books out there and some books are even better that way. Autobiographies, for example. A huge number of inspirational people read their own autobiographies now and it can feel like listening to a friend reminiscing about their own life.
Also listened to novels written in a similar style to yours. The rhythm of the words, even though they were not yours, it’ll seem to re-ignite some section of your brain and get you thinking creatively about your own ideas.
