“People who are rather more than six feet tall and nearly as broad across the shoulders often have uneventful journeys. People jump out at them from behind rocks then say things like, "Oh. Sorry. I thought you were someone else.”
― Terry Pratchett, Guards! Guards!

“Corporal Nobbs,” he rasped, “why are you kicking people when they’re down?” “Safest way, sir,” said Nobby. Nobby had long ago been told about fighting fair and not striking a fallen opponent, and had then given some creative thought to how these rules applied to someone four feet tall with the muscle tone of an elastic band.”

“Listen my hatchling, for now you shall hear
Of the only seven slayers a dragon must fear.

First beware Pride, lest belief in one’s might
Has you discount the foeman who is braving your sight.
Never Envy other dragons their wealth, power, or home
For dark plots and plans will bring death to your own.

Your Wrath shouldn’t win, when spears strike your scale
Anger kills cunning, which you will need to prevail.
A dragon must rest, but Sloth you should dread
Else long years of napping let assassins to your bed.

‘Greed is good,’ or so foolish dragons will say
Until piles of treasure bring killing thieves where they lay.
Hungry is your body, and at times you must feed
But Gluttony makes fat dragons, who can’t fly at their need.

A hot Lust for glory, gems, gold, or mates
Leads reckless young drakes to the blackest of fates.
So take heed of this wisdom, precious hatchling of mine,
And the long years of dragonhood are sure to be thine.”
― E.E. Knight, Dragon Champion
