Writer's Remorse

Does anyone recognize this?  I just got two poems accepted by a certain publication (whose editor had rejected them four months ago, but never mind--she contacted me, so why ever not?).  These are both poems I have shopped around for more than a year, and I think one of them is quite good.  Now that it/they will appear in print, I am wondering hard if I could have placed it in a 'better' publication, higher up on the writers' food chain.  Remember that it has not been picked up despite my sending it out some ten times.  Is there no end to the vanity of wanting to be published?
