Mr. Spadoni 

worked with a guy who, because of his parent’s work, had to move a lot. He got tired of packing the same stuff over and over, only to pack it up in a few months or a year. Finally, he just started throwing things in boxes before each move. No labels as to contents. When he got to the new house, if he was looking for say, a particular book, he’d open boxes until he found it. He’d repeat this for other items. After a few months, any boxes that remained unopened were dumped. He said this process saved him from having to decide which things he wanted just because and which things he actually used.
