"The best thing for being sad," replied Merlin, "is to learn something. That's the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honor trampled in the sewers of baser minds. There is only one thing for it then - to learn...Look what a lot of things there are to learn." - T.H. White, "The Once and Future King."
