The written word has its limits and its challenges, for the primal sound in the whole world is that made by the human voice, and the likeness of this human voice must be rendered in dots and strokes...Yet I never forget that the voice, too, is important...Don't mumble or hesitate. Speak...in a loud voice, clearly, and without fear.
If you want to really know something you have to observe or experience it in person; if you claim to know something on the basis of hearsay, or on happening to see it in a book, you'll be a laughingstock to those who really know.
