Ideas I Left Behind

I covet the ideas I left behind in altered states
When I was half asleep, over the limit, or baked.
As a writer, those ideas are something of a grail.
The their memory's shadow is tantalizing.  Reach for them and I fail.
However, I'd forget them in seconds.  There's something I miss more --
The people I like better in hindsight.  I was stupider before.
