Just so you know, in case no one has told you yet, writing is probably the most subjective medium there is. Or to put it colloquially, "One man's junk is another man's treasure." Like the others said, do not lose heart. In my own experience, it took me several years, and a whole lot of rejection letters, before my novel was accepted by a publishing house. As you can imagine, I was thrilled. About a month after my acceptance, another publisher I had sent my manuscript to several months earlier, finally responded. The editor hated it, spelling out in detail all the things wrong with the story. If I had gotten that letter a few weeks earlier, I would have been devastated. But since I had a publishing contract in my hand, I just smiled, and filed it with all the rejection letters. So you never know who is going to read your work and think it's dynamite. Pick yourself up and send it out again, and again, and again.
