When speaking of people, “the right sort” tends to have a very nasty usage, but when speaking of excess stuff, “the right sort” is the best way to get some really good organizing started. Typically, when one resolves to organize a cluttered basement or home office, there is a tendency to throw out not enough of what needs to go, too much of what shouldn’t go, and put the keepers into systems that won’t last. All of this can be solved by good sorting practices.
