That's how many final changes I submitted to the publisher today.  Everything ranging from: "This quotation mark is a beginning quotation mark, and should be an ending quotation mark" to "In this sentence, change the word from 'on' to 'in'."  

I swear this was the 50th time I've read my entire manuscript from beginning to end looking for layout errors, etc.  It will take a couple days before I get a new proof, which I'll spot check to make sure the final edits are all in there.  Then my artist will take a pass on the cover to ensure it conforms to the final template.  And then???

We're almost there.  

I live for the day when I can post a picture of the final, physical copy in my hands.
