Some of the best Mexican army proverbs I've heard:
They tried to bury us; they didn't know we were seeds.
There's no worse struggle than one that never begins. (In chess we know this as the threat is more potent than the execution).
The brave only lives as long as the coward lets him.
The right time to dine is: for the rich man, when he's hungry; for the poor man, when he has something to eat.
There's no deaf man whose than the man who doesn't want to listen.
Wounds from the knife are healed, but not those from the tongue.
