Katy speaks about the power of constraints and commitment devices which can help us move towards our goals. She refers to what Victor Hugo did when he was faced with a deadline in 1830 to publish his new book – The Hunchback of Notre Dame. When he had only 6 months left, Victor collected all of his clothes, removed them from his chambers, and locked them away. He was left with nothing to wear except a large shawl. Lacking any suitable clothing to go outdoors, Hugo was no longer tempted to leave the house and get distracted. Staying inside and writing was his only option. Katy speaks about the notion of commitment devices which borrows from this broad idea.
