Want to write a novel and looking for books or courses?
Before you buy a course on writing, I suggest you read books first. There’s a ton in Amazon! Granted, you’re probably need to read a lot. But if you’re going to buy for example, ten books, the total amount won’t be as expensive as buying a course. In fact, it’s just a small fraction of the a course price.
But other than the price, I think there are lots of great craft books out there that you really don’t need a course. (Unless the course gives you access to the course creator and you can ask questions and ask for feedback from them, not only from fellow writers.)
