There are few things more depressing than thinking of a great idea for a book, doing enough research to be sure that no one has written a book like it in 100 years, and then discovering a book that you didn’t see before that looks to be more or less the same as the book you want to write.
Your heart sinks, and you convince yourself that you’ll find your original idea someday.
But THEN, when you read the introduction to the book you just found, you see on the first page the words “secret brotherhood” and “Jesus.”
That’s when you know that you have discovered a book written by a crazy person.
That’s when you get back to work on your own book.
