Found elseweb: The Cowboy Hávamál, or, Old Norse wisdom translated into Wise Old Cowpoke†. A couple of brief samples:
You’re a goddamned fool
if you think you’ll live forever
just because you won’t fight.
Say nobody ever kills you –
old age is no peach, either.
Don’t think you’re the goddamned smartest,
or the toughest, or the best at anything,
and don’t let folks think you are, either.
Otherwise you’ll find out the hard way
that someone is always better.
†It’s one of the Three Faces of the Action Hero, which are like the Three Faces of the Triple Goddess, only different: The Kid, the Gunslinger, and the Wise Old Cowpoke. They can be seen all in one movie in the first Star Wars film, with Luke and Han and Obi-Wan (aka Old Ben) Kenobi, or serially over time in the television and film career of Clint Eastwood.
