Friedrich Nietzsche

I assess the power of a will by how much resistance, pain, torture it endures and knows how to turn to its advantage.

He who cannot give anything away cannot feel anything either.

The desire to annoy no one, to harm no one, can equally well be the sign of a just as of an anxious disposition.

But with each passing year and each new study, the evidence for the genetic contribution to individual and group differences becomes more firmly established than ever.

I'd date someone younger or older; age doesn't matter to me. Or looks, really - it's all about maturity.
