True friendship is like sound health the value of it is seldom known until it is lost.

Instead of loving your enemies - treat your friends a little better.

A true friend never gets in your way unless you happen to be going down.

Never contract friendship with a man that is not better than thyself.

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

Friends and good manners will carry you where money won't go.

Friendship is the source of the greatest pleasures, and without friends even the most agreeable pursuits become tedious.

It is important to our friends to believe that we are unreservedly frank with them, and important to friendship that we are not.

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

One of the most beautiful qualities of true friendship is to understand and to be understood.
