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

If you have one true friend you have more than your share.

I don't need a friend who changes when I change and who nods when I nod my shadow does that much better.

I value the friend who for me finds time on his calendar, but I cherish the friend who for me does not consult his calendar.

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

Never contract friendship with a man that is not better than thyself.

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

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

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.

Cherish your human connections: your relationships with friends and family.
