Bravery is doing something even though you are scared. You get no
points for doing anything that doesn't scare you.

I have done things others said later were brave. They were wrong. I did
things a mite more dangerous this very moment that improved the chance of my
ass still being alive 30 minutes late.

Anyone who sails, or races vehicles, or climbs mountains or flies airplane, on
bravery/courage is absolutely sure to crash and crash soon. running on courage
means you are running beyond your known capability.
