I keep a list for every year, at the end of my journal. I note what I sent, whom I sent it to, when I sent it, in black. If I get a nibble on it, I change it to blue. When it's rejected, I change it to red. When I get something accepted into a journal (or whatever), I change that to blue too. You can guess what that section of my journal looks like: a few lines of blue in a sea of red. Still, it works for me...
