I've been reading this topic (and other, similar ones). Man am I glad I don't have that to do all that (get rid of the stuff, sell the house, etc, etc)! I made a couple of major moves over the last 30 years or so, one from D.C. to Scotland, and then Scotland to Tacoma, WA. Those moves left me with very little in the way of tangible possessions. Since being back in the US I haven't bought a house, just mooched off Peter my son, well nor really mooched, at my insistence I pay for the privilege. All of my possessions, everything I own, I could probably squeeze into my Astro, though I won't, I'm still going to downsize some...
But it's not like I avoided anything, I just did it a lot earlier...
