A friend may well be reckoned the masterpiece of nature.

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

Friendship with ones self is all important, because without it one cannot be friends with anyone else in the world.

Real friendship, like real poetry, is extremely rare - and precious as a pearl.

Friendship is always a sweet responsibility, never an opportunity.

An excellent man he has no enemies and none of his friends like him.

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

Don't walk behind me I may not lead. Don't walk in front of me I may not follow. Just walk beside me and be my friend.

Cherish your human connections: your relationships with friends and family.

Caring for but never trying to own may be a further way to define friendship.
