Corrections are easily the least fun part of the writing process. BUT it means the end is near. This book had two great proofreaders, Tino Duran and Dyanne Khalaf. For good measure, I took a week to read the entire manuscript out loud. I'm now a little horse. Neigh.
Writing is never done. I think it's half the reason deadlines exist. Without a defined end point, it's too easy to write and re-write for an eternity.
