Friendship is essentially a partnership.
Without friends no one would choose to live, though he had all other goods.
Perfect friendship is the friendship of men who are good, and alike in excellence; for these wish well alike to each other qua good, and they are good in themselves.
My best friend is the man who in wishing me well wishes it for my sake.
Wishing to be friends is quick work, but friendship is a slow ripening fruit.
A friend to all is a friend to none.
Personal beauty is a greater recommendation than any letter of reference.
