We just had a company-wide powow, and the Chairman of the Board said something that resonated with me:

I want to work with guys who are going to get down in the fox hole with me and shoot.
And when the ammo’s gone, stab.
And when the knife’s dull, choke.
And when there’s no more war, drink tequila.

Couldn’t agree more.  Passionate, gritty coworkers are a blessing, and if you have them, consider yourself lucky.  If you don’t, maybe it’s time to find a better place to work.
