Picture a guy who owns a boat. He loves that boat. He keeps it waxed and clean, the rigging is always ready, the sails are bright and colorful, all the little bits and bobs are polished.
He puts on his funny little captain's hat, hops aboard, and does a quick check of everything. He's done well; this ship is fit to sail. A huge smile spreads across his face.
He unfurls the sails, sits by the tiller, and...
...sighs.
He's in the desert, and his ship is tied to a rock.
