I see that the fifth most popular resolution -- who surveys these things? -- is to read more. That strikes me as promising for those of us who like to write. My hope -- not resolution! -- is to complete and publish two novels in 2016, Wacky in WhoVille and Except for His Wings. Perhaps some of those people who want to read more will want to read one of those.
On the other hand, given that resolutions don't appear to have that much impact on behavior, maybe it won't help book sales at all.
I could resolve to be hopeful, though, right?
