No Pitch Like a Rejected Pitch

Y'know a few posts back how I had been working on a pitch with an artist?
We got rejected.
Bummer, man.
But it's a fact of life: most pitches are rejected.
So what now?
We're picking ourselves up and moving forward. I have a ton of ideas and my artist friend seems to like what I've got, so we'll keep at it. With luck, I'll actually get back into doing comics on a freelance basis.
Which would be way cool, as supplemental income would be real handy right about now...
