Some people put way too much stuff on their keychains.
I’m sure everyone knows someone who collects superfluous things on a split-ring that they miraculously squeeze into their pocket; someone who could lose their keys amidst all their dangling accessories.
I was once afflicted, too. I had useless trinkets, a massive aluminum armadillo bottle-opener, and keys to doors I hadn’t seen in years dangling from a split-ring.
Carrying that much stuff is unnecessary. It takes up valuable space, hinders efficient use of the things you do need, and usually looks a bit silly.
When it comes to keychains, minimalism works.
