Passion

If I were to wish for anything I should not wish for wealth and power, but for the passionate sense of what can be, for the eye, which, ever young and ardent, sees the possible. Pleasure disappoints, possibility never. And what wine is so sparkling, what so fragrant, what so intoxicating as possibility?

Soren Kierkegaard, Either/Or, as quoted in The Art of Possibility, page 113.
