Is There a One Linear Narrative?

The author used to commute on the train, writing chapters on his phone. He would wake up every morning and write for at least an hour. The one hour a day trick is the thing, like you'll hear on every leg self, helpsing as it an year,. You can't do that, it totally works. And i think there's nothin' special about non fiction -  i just do it in 30 minute increments.
