Diminishing returns

I
Felt like
I could get
A lot done today
But here it is at
The end of the day and
I don't know that I did so
Much.
I'm tired.
I want to
Do more but my
Brain has gone on strike.
It's telling me to rest and
recuperate.
But I
Still have several
Things I have to
Do tonight before I'm done.
A
Meeting and
Feeding the kid
And feeding the animals.
And
Really so
Many more things.
But
I'm out
Of brain power.
Things
Are shutting
Down.
