Shut up & write!
Shut up & write is a method that helps you write when you lack the discipline.
The model is simple: writing for 45 minutes, followed by a 15 minute break, followed again by 45 minutes of writing. By structuring your time this way, you will achieve at least two things: inspiration to work when others work, and a clear conscience when taking a break.
Bring your own laptop with your writing project. Coffee be served during the break.
