I'm kind of disappointed to learn that I didn't invent the word concretize.
Yesterday on the way home from a reading in Brooklyn I wrote this in my notebook, which because I was in a certain kind of mood (a good kind) I wrote as lines of poetry:
Like anyone I sometimes get these flashes of insight
as I'm walking around or
sitting on the train or something but I don't like to
write these things down, to concretize them the way everyone advises
in books about how to write.
Then I wrote some other stuff that wasn't very interesting.
I wish I was smarter. I probably don't even know what concretize means.
