It shouldn't be a warehouse

Have you ever wondered how museums decide what to put in them? It’s actually quite simple: first, they decide what not to put. Thus what’s left… that’s the valuable stuff.
And that’s what makes a museum different from a warehouse. Because a warehouse is a place where people put stuff. Lots of stuff. Indiscriminately.
So who makes a museum valuable? A curator by actively discriminating what gets in.
There are lots of warehouses out there, but your product could become scarce by thinking about it like a museum… In short, leave stuff out, and focus on the essentials.
(P.S. I’ve stolen this metaphor from a great talk by Jason Fried.)
