Not a great deal is known about the factors in childhood that doubtless underlie a person's choice of career - I'm talking now about a career to which one is passionately committed, in contradistinction to a career chosen merely as a means of earning a living.

To love a person is to know and love the person. But we can pick up an enormous amount about another human being just by exchanging a couple of sentences. It's not yet knowledge; it's an intuition that motivates you to want to find out more.

Of all the nonsense written about love, none is more absurd than the notion that ideal love is selfless. To love is to see myself in you and to wish to celebrate myself with you. What I love is the embodiment of my values in another person. Love is an act of self-assertion, self-expression and a celebration of being alive.

Romantic love can be terrifying. We experience another human being as enormously important to us. So there is surrender - not a surrender to the other person so much as to our feeling for the other person. What is the obstacle? The possibility of loss.
