timeless shipwreck parable

if you were shipwrecked on a cookie island, your initial reaction would be, "wow, what a fantastic bit of good fortune." you would be ignoring , at least initially, how unlucky you were to be in a shipwreck at all, but heck, landing on a huge cookie is not the worst way for that to play out. you would eat the cookie when you first "beached" because there is plenty of cookie, it tastes good, you are hungry, and you had a bit of recent bum luck, so hey, why not? why shouldn't you? but after awhile, you would eat the cookie, to not just stave off hunger, but to stay alive. and the island would grow smaller as you ate more and more of it, until one day all that would remain of cookie island would be better described as, cookie pedestal, and if you eat any more, the island will be too small to support you, and you would certainly drown; but if you don't eat it, you certainly starve. it all sounded so rosy to begin with, again, not counting the shipwreck itself.
