Barring some twist that I can't imagine, I'm declaring my PhD thesis finished as of now. I gave it a final (hopefully) proofread tonight, so now I just need to print off copies of the final, final, ultimate version of this last draft, then get them bound, and get the appropriate forms signed so I can hand it in. It's going to be hard to let go of it after four years. There's always the thought that maybe there's some last improvement to make. But by this time next week I should have done everything that needs to be done ... and will just be awaiting the responses of the examiners.
It's too early to celebrate quite yet, but we're getting very close.
