Next job: United States Navy (age seventeen). Served on three different ships; ran ship's library, was drunk in many foreign and domestic ports. Read all of Shakespeare, Milton, Faulkner, Conan Doyle, Fitzgerald, Jane Austen, a few dozen others and as much of the Brontes as I could take.
Knowledge and Skills Obtained: Learned many impressive new curses in English and other languages; found out why the rest of the world craves American cigarettes; discovered that most of the world is poor. Avoided sexual relations with prostitutes around the globe. Managed to quit smoking. Found that they still have a silence rule in Australian libraries.
