Never judge from appearances.
Never say die.
Never too old to learn, never too late to turn.
New wine in old bottles.
No cross, no crown.
No garden without its weeds.
No living man all things can.
No man can do two things at once.
No man is born wise or learned.
No man is content.
No man is wise at all times.
None are so blind as those who won't see.
None are so deaf as those who won't hear.
No news is good news.
No one can call back yesterday.
No pains, no gains.
No pleasure without pain.
No rose without a thorn.
No sweet without sweat.
No smoke without fire.
Nothing brave, nothing have.
Nothing dries sooner than a tear.
Nothing in the world is difficult for one who sets his mind to it.
Nothing is difficult to the man who will try.
Nothing seek, nothing find.
