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

A man's friendships are one of the best measures of his worth.

Friendship is a strong and habitual inclination in two persons to promote the good and happiness of one another.

It is not so much our friends' help that helps us, as the confidence of their help.

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

The greatest gift of life is friendship, and I have received it.

Friendship is the shadow of the evening, which increases with the setting sun of life.

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

My best friend is the one who brings out the best in me.

Wishing to be friends is quick work, but friendship is a slow ripening fruit.
