" Here is Lee De Forest addressing young people on the joys of the wireless: If you haven’t a hobby—get one. Ride it. Your interest and zest in life will triple. You will find common ground with others—a joy in getting together, in exchange of ideas—which only hobbyists can know. Wireless is of all hobbies the most interesting. It offers the widest limits, the keenest fascination, either for intense competition with others, near and far, or for quiet study and pure enjoyment in the still night hours as you welcome friendly visitors from the whole wide world.10 "
