"On Twitter, I asked my fellow professional organizers what they thought — and they were unanimous in giving this a thumbs down. You can see their comments here: https://twitter.com/JeriDansky/status/1483588857656328195"
"Matt, I definitely agree about not keeping things you don't need (or love); as a professional organizer, I always work with clients to declutter before we worry about storage. And certainly many things should NOT be stored in the attic; I've seen too many things ruined by being stored in a hot attic. Your other cautions are right on, too. But sometimes the attic can be used well (assuming it's safe). For example, many people like decorating for the holidays, and many of their decorations will not be harmed by attic storage. "
