If you have one true friend you have more than your share.

Peace, commerce and honest friendship with all nations entangling alliances with none.

That friendship will not continue to the end which is begun for an end.

Never explain - your friends do not need it and your enemies will not believe you anyway.

There is nothing on this earth more to be prized than true friendship.

As iron sharpens iron, so a friend sharpens a friend.

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

Depth of friendship does not depend on length of acquaintance.

Since there is nothing so well worth having as friends, never lose a chance to make them.

A friendship founded on business is better than a business founded on friendship.
