The language of friendship is not words but meanings.

There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

You can always tell a real friend: when you've made a fool of yourself he doesn't feel you've done a permanent job.

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

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

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

Friendship at first sight, like love at first sight, is said to be the only truth.

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

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

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