SEPTEMBER 21. Bumble bees give up on stems without flowers; wild animals give up on forests that are on fire; birds give up on trees without edible fruit; thieves who elude capture give up and throw away their past. Khmer.

Wild dog, do not pretend to be king of the lions; common bird, do not pretend to be king of the swans; dumb and ignorant one, do not pretend to be wise; vigorous baku, do not imitate the woodpecker.
