I’m currently teaching creative writing for Penguin Random House (Writing for Beginner's and currently Constructing A Novel), the Open College of the Arts (Writing Skills and Scriptwriting) and elsewhere. I often have students asking questions along similar lines and having written some blogs on the various aspects of creative writing I thought I should create a go-to place where these resources can be easily found. So without further ado here is the main link- https://weareoca.com/author/guy-mankowski/
And here are links on various subjects (links in bold). There are also on the above link many other pieces on various subjects to do with being a writer, such as on getting your work published, touring to promote your work, but below are the links that are perhaps most educational.
