Anton Chekhov

Love, friendship and respect do not unite people as much as a common hatred for something.

Don't tell me the moon is shining; show me the glint of light on broken glass.

Knowledge is of no value unless you put it into practice.

I was good at being a doctor; my patients liked me. At times people trust you with things they wouldn't tell their spouses. It was a real privilege.

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.

It took me realizing that a broken heart has never actually killed anyone to find the courage to ask for what I want, in just about every situation. That was part of my own growing up.
