Every moment of happiness requires a great amount of Ignorance

Several sorts of memory exist in us; body and mind each possesses one peculiar to itself. Nostalgia, for instance, is a malady of the physical memory.

Among even the happiest married couples there are always moments of regret.

But also remember: if you have any genuine feelings, hide them like treasure; never let anyone so much as suspect them, or you're lost. Instead of being the executioner, you'll be the victim. And if you ever fall in love, keep that absolutely secret! Never breathe a word until you're completely sure of the person to whom you open your heart. And to protect that love, even before you feel it, learn to despise the world.

Do you know how a man makes his way here? By brilliant genius or by skilful corruption. You must either cut your way through these masses of men like a cannon ball, or steal among them like a plague.

Everybody all over the world takes a wife's estimate into account in forming an opinion of a man.
