"I am perhaps happier now than I have ever been and yet I cannot but recognise that I would trade all that I am to be you, the eternally unhappy, nervous, wild, wondering and despairing 16-year-old Stephen: angry, angst-ridden and awkward but alive. Because you know how to feel, and knowing how to feel is more important than how you feel. Deadness of soul is the only unpardonable crime, and if there is one thing happiness can do it is mask deadness of soul."
