I have a few favorite things.  Near the top of the list, right below Girls in White Dresses With Blue Satin Sashes, is typing THE END on the last page of a first draft.

 This morning I did that with the latest story in the Larenfall Cycle.  Finished the epilogue (which we seem to collectively call the 'post credits scene' nowadays) and sat back, triumphant.  It's sitting around 52K words right now and we'll see what survives the editing process.  Soon I'll be recruiting beta readers and getting feedback.  Hopefully I'll have it complete by the time Gen Con rolls around in August.
