That's the trade-off all right. A lot of the extra time that you spend packing your own stuff is looking at every single thing and deciding whether you really want to move it, or sell it or trash it instead. It's a lot faster to just pack everything without having to think about that. Having all of the boxes of the right types and all of the packing paper that you need at hand helps too.

But then, yeah, you do end up with a lot of stuff you don't need if you aren't forced to prune like this ever so often.
