No man can be happy without a friend, nor be sure of his friend until he is unhappy.

Those who are unhappy have no need for anythingin this world but people capable of giving them their attention.

I am one of those unhappy persons who inspire bores to the greatest flights of art.

No one is completely unhappy at the failure of his best friend.

If you optimize everything, you will always be unhappy.

Unhappiness is not knowing what we want, and killing ourselves to get it.
