With apologies to Jonathan Coulton.

This was a triumph (of experience over optimism)
I’m making a note here, (because my memory is awful)
“Huge Success!” (came from being realistic)
It’s hard to overstate my satisfaction

Aperture Science (has given me many hours of enjoyment)
(Although I hope we never see anything like it in the real world)
For the good of all of us
Except the ones who are… (OK, I’m going to stop you there, GLaDOS)

Nothing good can come from following too closely
In the footsteps of people like Cave Johnson
And so my filk departs, and my own voice is heard,
Wittering on, without metre or rhyme
In a sleep-deprived haze of happiness
That comes of setting an attainable goal

I shall now stop talking, for there’s sleeping to do
Then tomorrow morning, I’ll start reading on through
All the poems posted here, from this and other years
But for now, I’m barely awake.

P.S. I feel exhausted, but I’m still awake!
P.P.S. This isn’t healthy, to be still awake.
P.P.P.S. Oh look, the filk’s back. Am I still awake?
Still awake.
Still a-

My book was Garden by Zhou Fang, and the first line of actual text is just the word “Nothing”. The poem/filk above does contain that word, so I’m counting this as a technical prompt response, even if it was far too easy. 😁😃😄
