One particular article of Dean Wesley Smith’s is this one where he discusses Heinlein’s Rules for writing. Specifically, the discussion of Rule #4 – Mail the story to an editor who will buy it.
He talks about a workshop where they had everyone bring what they thought was their best work, and their worst work, put it in a bin, and then make an anthology out of the works that are in the bin, and the participants were not allowed to use their own work. Read the article. The results are interesting, and have sparked some of this introspection about my work that’s going on right now.
