It is an ill wind that blows nobody good.
It is never too late to learn.
It is not the cowl that makes the friar.
It is a long lane that has no turning.
It's a good horse that never stumbles.
It's a sad heart that never rejoices.
Ill weeds grow apace.
Keep a thing for seven years, and you will find a use for it.
Kill two birds with one stone.
Lazy folk take the most pains.
