This video introduces a writing technique called "borrowing from the future" to overcome writer's block. The speaker explains that when encountering a scene that's difficult to write, writers can insert a placeholder description and move on. This technique, supported by the Zeigarnik effect, allows the subconscious mind to work on the problem, leading to new ideas and maintaining writing momentum. The video also uses examples from art history and literature, such as Leonardo da Vinci and J.R.R. Tolkien, to illustrate how this method of deferring perfection and allowing for changes can lead to richer, more developed works.
