One of my best productivity hacks is the use of the Pomodoro timer. 25 minutes on, 5 minutes off.
It’s the psychology that’s so good. “Sure, I can focus on writing for 25 minutes.”
Even better is having a Pomodoro Buddy. Find someone equally frustrated with writing, meet at a coffee shop and keep each other in check for 25 minutes at a time.
Been working wonders lately.
