Don't put off till tomorrow what should be done today.
Diligence is the mother of success.
It's never too late to learn.
Walls have ears.
Wash your dirty linen at home.
Waste not, want not.
Weak things united become strong.
Wealth is best known by want.
We can't judge a person by what he says but by what he does.
We only live once, but if we work it right, once is enough.
What is done by night appears by day.
When a man is going down-hill, everyone will give him a push.
When children stand quiet, they have done some harm.
