That seems like an overstatement. Foremost? Johnson said that a writer may turn over half a library to make one book, but this article doesn't talk about doing anything with your collection after you've curated it. The creative act referred to in this article seems to be the curating itself. That's fine as far as it goes; curation is a form of creativity. But I'd say creators, broadly, are first and foremost people who make stuff, not people who curate other stuff. If you're too overwhelmed by stuff to make anything yourself, you've probably seen plenty already. Maybe shut off the firehose and try working on something before deciding lack of curation is the problem you face. This feels a bit like the impulse that tells you the reason you can't get any writing done is because you need to clean your office first.
