We have already noted that dragons are present in Hvergelmir, the well of creation, where they gnaw at one of Yggdrasil's roots. Another dragon we must consider is Jormungand, the Midgard Serpent, Thor's greatest enemy, who encircles the world and grasps his tail in his mouth. By striving for personal excellence, one need not defeat life's foes in a physical, secular sense in order to have a meaningful existence. The Nordic hero cherished existence and knew how to enjoy life, but he could also face death with a calm mind and a smile. No matter what happened, a hero could choose to behave with honor.
Every man is mortal.
But the good name will never fade Of one who has lived honorably.
