What To Invent
Cheap, useful articles that will sell at sight.
Something that everyone needs, and the poorest can afford. Invent
simple things for the benefit of the masses, and your fortune is made.
Some years back a one-armed soldier amassed a fortune from a single
toy--a wooden ball attached to a rubber string. They cost scarcely
anything, yet millions were sold at a good price. A German became
enormously rich by patenting a simple wooden plug for beer barrels.
