Friendship is always a sweet responsibility, never an opportunity.

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

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

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

Friendship... is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.

I always felt that the great high privilege, relief and comfort of friendship was that one had to explain nothing.

Success always necessitates a degree of ruthlessness. Given the choice of friendship or success, I'd probably choose success.

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

An excellent man he has no enemies and none of his friends like him.

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