A river can only boast when it is full of fish.

It is in vain to drown a fish, no matter how deep you submerge it.

Only dead fish allow the sea to carry them to and fro.

If you cast your bait after the fish have passed, you will only catch despair.

If you throw a crumb to hungry birds, they will harm each other fighting for it.

Never burn a bridge while you are still crossing it.
