You can't pretend to be witty because wit is dry, subtle, lacerating, cynical, elitist, and risque - all impossible to fake. Humor, on the other hand, is broad, soothing, positive, inclusive, and smutty - to make sure everybody gets it. Pretending to be humorous is easy, and a great many people are doing it.
What I treasure most at any moment is intimacy, surprise, a sense of mystery, wit, depth and love. A handful of cherished friends offer me this, and the occasional singer or film-maker or artist. But my most reliable sources of electricity are Henry David Thoreau, Shakespeare, Melville and Emily Dickinson.
