I saw this concept discussed in the book Big Magic, and I also saw a video online talking about how Micheal Jackson use to get in the studio quickly because he was scared that God would give the idea to Prince.
Even the authour of the invisible life of addie la rue did an interview where she said that she realized she had to write Addie or the idea would go to somewhere else.
As someone who is creative at heart but struggles with execution this idea has always stuck with me. Can be fiction and non fiction
