There is no gratitude from the wicked.
The fish will soon be caught that nibbles at every bait.
The grass is always greener on the other side of the fence.

A forced kindness deserves no thanks.
He is rich that has few wants. (He is richest who has fewest wants.)
The worth of a thing is best known by the want of it.
