No, I do not know this. I've moved ~29 times in my life. I've never once had a problem unpacking. I packed up shelves and drawers and dressers and closets. When I get to the new place I open a box, see what's in it, "oh, this was the stuff in bedroom drawers" so I go put the stuff in there in just a few seconds. In a few hours I'm 100% unpacked.
I've never really understood why it would be any different for anyone else except if maybe if they moved to a much smaller place.
Is it really that common of an experience?
More to the point of the article though - I'm not entirely sure I want to unpack my job - I feel like lots of people would not "do the thing" if they knew how hard it would be. But, looking back, they're proud they "did the thing". I know for me, I started some companies and projects years ago. I was able to do this because I didn't know how much work it would be. Now that I know, I find it extremely hard to get started again. I wish I could go back to my old naive self.
Maybe a better example, all though one I have unfortunately not experienced, would anyone have kids if you "unpacked" what having kids is actually like? I think you could list 100s or 1000s of "unpleasant on paper" things but I don't really think you could write the positives in a compelling way against that list of negatives. And, yet I believe the majority of parents would tell you having children was the most fulfilling thing in their lives. I think many of the things mentioned in the post might also have a similar issue.
