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

Friendship may, and often does, grow into love, but love never subsides into friendship.

Am I not destroying my enemies when I make friends of them?

Lots of people want to ride with you in the limo, but what you want is someone who will take the bus with you when the limo breaks down.

Nothing so fortifies a friendship as a belief on the part of one friend that he is superior to the other.

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

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

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

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

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