From Oliver de la Paz' blog:

Currently in the throes of putting together small manuscript packets to send out to journals. What I'm finding is I'm running out of stuff that holds my confidence. I suppose this is natural--a lot of the stuff that has my confidence is either picked up, out, or in limbo somewhere.

I'm feeling something along the same lines, and it's reassuring to know that someone I admire so much goes through the same process. If you have a minute, the rest of the post is very interesting, as de la Paz goes on to discuss how he views his individual poems in terms of book-length works and how that affects his submission process.
