Over 90% of writing is making things just for fun. Over 90% of story writing is making things that don't work in order to get to what works.

Writing is more of a craft than it is a skill. You can have as much skill as you want, you're going to end up with bad drafts or things you cranked out. It's the craft and commitment that's going to get you where you want to be. The best thing you can do as a writer is realize there's no such thing as writer's block, and writing is about... Writing. A lot of times you just have to write what makes you happy. With things like books, most of the time will be spent doing things that don't work or things you end up not liking in order to get through all the layers. Don't give up, write every day or at least attempt to in order reach What you want sooner.
