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

Let there be no purpose in friendship save the deepening of the spirit.

One's friends are that part of the human race with which one can be human.

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

I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.

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

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

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

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

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