How much stuff is enough?

As is the case with each of our moves, one gets to be an expert at packing and organizing stuff even before the packers arrive. While I leave the bulk of the packing to them, I have to go through and sort out stuff so that I can decide what to keep and what to get rid of. It's a time consuming process and with each move we are getting a bit better at it. We're also not buying things just because they can be bought, but now really consider if we need it, or are getting it just for the heck of it, or if it's on a substantial discount. One really needs to think of what one really needs after all, and they are very few things if you really get down to it.
