Jack, my favorite.

"...My struggle was this. You may well believe that I had set out sad enough; I came on a sad errand. Now, flung at me like frolic or insolence, there came as if it were a voice- no words- but if you made it into words it would be, "Why should your heart not dance?" It's the measure of my folly that my heart almost answered, "Why not?" I had to tell myself over like a lesson the infinite reasons it had not to dance. My heart to dance? ... and yet, it was a lesson I could hardly keep in my mind. The sight of the huge world put mad ideas in me, as if I could wander away, wander forever, see strange and beautiful things, one after the other to the world's end. The freshness and wetness all about me (I had seen nothing but drought and withered things for many months before my sickness) made me feel that I had misjudged the world; it seemed kind, and laughing, as if its heart also danced."
