A Chinese sage once said:
One grain of sand does not make the shore
Good habits bareforth good fruit. . .
Noble thoughts are not alone. . .
What's good for the goose's not always good for the gander. . .
A stitch in time saves nine. . .
People who live in glass houses shouldn’t throw stones. . .
Tell no tales and you'll get no lies. . .
Foolish boys should not ask stupid questions. . .
Rolling stones gather no moss. . .
A bird in the hand's worth two in the bush. . .
One man's cure might be another man's poison. . .
