I've been taking a lot of photos this year. The count in my Lightroom library is over 13,000 for the year. Now, there are multiple copies of some photographs, but there are also a lot that I've deleted.
Recently, I've been distracted playing a computer game (Dragon Age, fun game), so I've been very slow to process things. I also need to get a little better disciplined about reviewing the photos right after I take them. Pare down the list of the things that are good, and things that aren't, process the former and delete the latter.
The sheer number of them gives me pause. I remember what a consultant I worked with said "How do you eat a whole elephant? One bite at a time."
