I'm the opposite. I am selective, but it's work to decide what's worth keeping, especially if you are prolific with your camera. However, two years later I have more emotional distance and have grown as a photographer, and it's easier to discard swaths. Bulk storage plus time makes easier.

It's the same approach I take with tax documents. Roughly group by year, yes, but why carefully select which ones I have to keep now, when I can just throw all of them out in a few more years?
