Think you have enough shelves? WELL YOU'RE WRONG
Shelves are where we keep our stuff. The more shelves we have, the more stuff we can put on them. It's very simple math, really. And can you ever really have enough stuff? No! What if you lost some of the stuff, or found some really cool new stuff. The acquisition of stuff is just part of being a human- so get some more shelves for your stuff.
