Yeah, I struggle with self-editing too.
My wife will tell you I'm a packrat.
I don't like to get rid of things - including photos. There are many that I *should* delete, but don't. About the only things I delete immediately are white balance calibration shots, accidental snaps from hitting the shutter release as I'm picking up the camera, and unsalvageable focus/exposure errors.
The "winners" get printed, and everything else gets stored for a later look. Somehow I tell myself that maybe I'll see a better way to crop or otherwise improve a shot if I put it away and look at it later. That rarely happens. I wish I could be more decisive.
