It was always funny to me that dragons hoard gold.
In almost every story we have about a dragon, they harbour some deeply valuable and important treasure; the hero must outwit or outfight the beast to get it.
What does a giant flying lizard want with a pile of shiny metal or a bejewelled cup?
Dragons are a storytelling device; an ancient meme designed to teach us about life. They always hoard treasure because the thing we want the most is always where we least want to go.
If we want the gold, we must first leave our comfortable castles and slay the dragons of chaos within us.
Only then, can we live happily ever after.
