I'm still stoked after publishing my first novella, <a href="https://www.smashwords.com/books/view/330341">The Minstrel</a> through the <a href="http://www.smashwords.com">Smashwords Website</a>.
I'm currently editing my first novel, which I started much longer ago than I care to admit.  This epic-length tale of horror has undergone many revisions since I first conceived of the story, and this version is by far the best.  It seems the time writing other stories (the aforementioned novella as well as two other novels currently in development) gave me enough time off from that particular work to gain a fresh perspective.  Originally close to 300k words, I've been cutting through it like a scythe, and the result has been a leaner, cleaner narrative.
It's funny, in a way.  When I finished the first draft (and every draft thereafter) I would look down on my creation and say 'it is good'.  But after time away from it, I could see huge plot holes, as well as long expositional paragraphs that were completely unnecessary.  I will cut at least 25-30% of the word count by the time I finish.  Four chapters are in the can, and the chapter count may even change by the end (currently 22 and an epilogue).
