I think I just don't have an 'eye' for what makes a good photograph.
I have taken some photographs I love, but they aren't technically good and are only good to me (because of the memories with the photo or who is in the photo).
It's annoying as I love it, and I love going out and practicing more. I've read lots on composition etc and how to use my camera but I find it so hard to actually picture the scene in my head and what will make a good photo.
Also, what are peoples throw away rates like? If I go out for a day with the camera and take say 20 photos. I might save 1.
