How to Write a Book - You Should Have a Question

I've been reading this book recently. It's called better never to have been. And it was written by a philosopher in south africa, in cape town named benitar. He basically argues that because life is so full of suffering, even good lives are very much full of suffering. But i don't think he wrote it backwards. I think he came to that conclusion and then wrote the book to justify it - which is actually the reverse of the way you should write a book.
